Being overly nice isnt being nice, its being intrusive. How nice people are to each other has to be mutually agreed upon, otherwise things get unbalanced?

Like if two people agreed to buy each other coffee, one does monday, the other does friday. Then if one started buying coffee for both also on tuesday, wednesday, and thursday, well, that wasnt the deal. Maybe the other person has other plans. So its not being nice, it turns out more like being bossy.

Does this help explain it?
