What happens in the video
Hana doesn't accept Nadia's excuse about three exclamation marks and says it straight: "I don't believe you." Nadia blames a very excited laptop. Later Hana tries a softer question, "Are you sure it was an accident?", and this time Nadia admits a little more. Watch the Short to hear how a gentle question works better than a direct accusation.
1 Are you sure you're okay?
Tone Gentle, open question
Use it when someone says they're fine but you think they aren't. It gives them a chance to rethink. Don't use it about facts or numbers; it's about how a person feels.
Papa, are you sure you're okay?
For example:
A: I'm fine. I just didn't sleep much.
B: Are you sure you're okay? You look really tired.
A: Well, maybe I'm a little stressed.
2 Can you explain that?
Tone Polite and curious
Use it when a story or claim doesn't make sense to you and you want details, not a fight. Say it in a calm voice. A sharp tone can make it sound like an accusation.
Can you explain that?
For example:
A: The report is late because the printer deleted it.
B: Can you explain that? I didn't know printers could delete files.
A: Okay, I forgot to save it.
3 I'm not convinced.
Tone Calm but firm
Use it when you've heard the explanation and you still have doubts. Convinced means sure that something is true. It's clear and honest, so use it when you're ready to say what you think.
I'm not convinced.
For example:
A: This plan will save us a lot of money.
B: I'm not convinced. Can we look at the numbers again?
4 Are you sure about that?
Tone Light, questioning
Use it when you think a fact or detail may be wrong. It's softer than "That's not true." With friends it can sound playful; with a manager, keep your voice neutral.
For example:
A: The meeting starts at ten.
B: Are you sure about that? The email said nine.
A: Oh, let me check.
5 I find that hard to believe.
Tone Polite but doubtful
Use it when a claim seems very unlikely. It's more direct than a question, so it fits when you want the person to know you have real doubts. It can sound cold if you say it to a friend who is upset.
For example:
A: I finished the whole book in one hour.
B: I find that hard to believe. It's four hundred pages.
6 That doesn't sound right to me.
Tone Soft, personal doubt
Use it to question information without saying the other person is lying. The words "to me" make it your opinion. It works well at work and in groups.
For example:
A: We only sold ten tickets last week.
B: That doesn't sound right to me. I think it was closer to fifty.
A: You might be right. I'll look again.
7 Is that really what happened?
Tone Curious, a little skeptical
Use it when someone tells a story and some part seems missing. It invites them to tell the full story. Avoid it in formal complaints, where it can sound like blame.
For example:
A: The cat broke the vase all by itself.
B: Is that really what happened?
A: Fine. I helped a little.
8 Really? That's surprising.
Tone Friendly, mild doubt
Use it in casual talk when something surprises you and you're not fully sure it's true. It keeps the mood friendly. It's too weak if you need to question something serious.
For example:
A: I've never been late to work.
B: Really? That's surprising. Not even once?
9 I'd like to see that for myself.
Tone Calm, practical
Use it when you want proof, such as a document, a photo, or a result. It sounds reasonable, not angry. Don't use it about someone's feelings.
For example:
A: The new version is twice as fast.
B: Great. I'd like to see that for myself. Can you show me a test?

Questions learners ask
Is "I don't believe you" rude in English?
It isn't always rude, but it's very direct. Between close friends it can sound playful. With coworkers, clients, or people you don't know well, a question like "Are you sure about that?" or "Can you explain that?" is safer.
What's a formal way to say "I don't believe you"?
"I'm not convinced" and "I find that hard to believe" both work in formal settings. You can add a next step to keep things polite. For example: I'm not convinced. Could we look at the data together?
What's the difference between "I'm not sure" and "I'm not convinced"?
"I'm not sure" often means you don't know. "I'm not convinced" means someone tried to show you something is true, and you still have doubts. It's firmer and fits after you've heard an explanation.
How can I sound less aggressive when I doubt someone?
Ask instead of tell, and keep your voice calm. Words like "to me" and "really" make your doubt sound personal and curious. Giving the person a chance to explain usually gets you a more honest answer.
