1 Just keep the peace.
Tone Gentle, friendly advice
Use it when you want someone to help people stay calm and happy, for example at a family dinner or in a team meeting. It is not a good choice when someone has a real problem that needs to be discussed.
Just keep the peace.
For example:
A: My brother and my uncle always argue about money.
B: It's only one evening. Just keep the peace.
A: Okay. I'll change the subject if they start.
2 Just don't make waves.
Tone Casual, quiet warning
Here, waves means trouble that people notice. Use the line to tell someone not to attract attention or create problems, often in a new job or group. It can sound a little cynical, so avoid it when the other person is trying to fix something unfair.
Just don't make waves.
For example:
A: It's my first week. Any advice?
B: Learn how things work first. Just don't make waves.
3 Don't rock the boat.
Tone Firm, keep things calm
Use it when things work fine now and a change or complaint could upset the situation. It is direct, so with a manager or a client a softer line like "Let's not change too much" may be better.
Don't rock the boat.
For example:
A: I want to suggest a new schedule for the whole team.
B: Everyone finally likes the current one. Don't rock the boat.
A: Fair point. I'll wait a few months.
4 Let's not stir things up.
Tone Soft, inclusive suggestion
Use it when a topic or comment could start an argument again. "Let's" makes it sound like a shared decision, so it works well with friends and coworkers.
For example:
A: Should I reply to her angry email?
B: She's calmed down now. Let's not stir things up.
5 Leave well enough alone.
Tone Practical, slightly firm
Use it when something is good enough and more changes could make it worse. It is about improving or fixing things, not about arguments between people.
For example:
A: The report looks fine, but I could rewrite the introduction again.
B: The boss already approved it. Leave well enough alone.
6 Let sleeping dogs lie.
Tone Wise, idiomatic advice
Use it about an old problem or disagreement that is quiet now. It means don't bring it back. It is an idiom, so explain it if your listener is new to English.
For example:
A: Should I ask him about the fight we had last year?
B: You're friends again. Let sleeping dogs lie.
7 Keep your head down.
Tone Cautious, protective advice
Use it to tell someone to do their work quietly and avoid attention, often during a difficult time at work or school. It sounds like friendly protection, not an order.
For example:
A: There are rumors about job cuts.
B: Keep your head down and finish your projects.
A: Good idea. No big changes from me this month.
8 Don't start anything.
Tone Direct, a bit stern
Use it when you think someone may begin an argument or a fight. It is strong, so use it with people you know well, not with clients or new colleagues.
For example:
A: Is your ex coming to the party?
B: Yes. Please don't start anything.
