Answer 1

No...this will break ur relation

Answer 2

False.

It is not okay to react to their annoying behaviour without knowing the reason why they are behaving like that.

Try to talk them politely and understand their problem. And then, try to know the reason why they are behaving like that. And if possible,try to resolve their problem.

This will help not only to  sustain your relationship,but also makes your relationship/bond stronger.
