You've probably suspected for a while that you're a People Pleaser. Every time you go out with that friend you no longer really want to keep in touch with. Or every time you agree to babysit your cousin's dog (even though you're not much of a fur-lover yourself). Or whatever this scenario involves for you. 

你可能曾经怀疑过自己是不是好好先生。比如在每次你和不再想联系的一位友人约会时，又或者你答应一位表亲帮他/她照顾狗狗时（虽然你自己并不是一位爱狗人士），你总是陷入要当好好先生的境地。

You say "yes" to make other people happy. 

你答应对方，取悦别人。
