If you were pissed at somebody Would you consider contacting them in a couple of months?

If say you were mad at someone would you cut it off for good or were there instances where you spoke to them again? Most often if somebody treated me badly and come back later I’ll not welcome it. But I heard some people are cool with it if some time has passed
