Is there an expression to use when someone does not do something or does something, because, for example, he does not want to offend that person or upset him.
For example, your close friend asks you to do something. You don't really want to do it, but you do it, because you think if you don't, he will get upset.
Is there any expression defining the act?
Or is there one that describes the type of relationship between you and your friend? Describing a relationship in which one side finds it really hard to refuse the other's request fearing he might get upset.
A: She asked you to do her homework and you did it again?!
B: Well, yes. I didn't want to upset her. (Something that B can say about himself and the way their relationship is)
I'm not sure if saying the person is "constrained by reserve" can fit the context. Cause might sound weird if B says "I'm usually constrained by feelings of reserve in my friendship with her."
