Depends on the relationship I have with a certain person. Sometimes I have people I usually get into fights and then a few days later I completely forget it about it;Then I be nice to that person again.(rinse and repeat)
Then I have people who I pretended I kinda of know, but in reality we don't really care about each other .
I also have strange times when someone offends me and I overreact to it(that's why I get into the 1st relationship I mentioned) or if the person tries to explain why they aren't offensive by making a sob story that has nothing to do with the subject,then I be rude to you since you are an obvious troll.
Then I just have people who I just seem to always agree to, so as imaged I get along with them just fine.
Etc.....Again depends on what type of relationship I have with them.
