Do you know when to stop?

By when to stop, I mean stop flirting, nagging, irritating or joking with someone.
I do and I believe there are times when you should stop.
1. When the other person says stop.
2. When the other person is busy in something important.
3. When the other person is feeling uncomfortable because of you.
4. When you are certain or you find out that they are in a committed relationship.
5. When the other person is sad Or depressed because of loss of someone or something.
Basically know your boundaries and be decent.
Valentines is right around the corner so don't push too much as no means no.
And I hope you know when to stop, do you?
