O, I don't know...I'm a 9 and I LOVE helping people. Sometimes I stop people on the street just to see if I can help them in someway.
I suppose though, I am not very interested in helping with "chores" and yes, if people begin to "expect" me to do things I'll immediately rebel and stop, especially if it's not being appreciated.
However, if a chore needs to be done because someone can't (due to some illness or other problem) I would take joy in doing it for them. Even if this "chore (s)" meant taking care of someone sick for a long period of time.
I'm a 9, I don't know anything about 2's...
I don't like conflict, not because I'm afraid of it, or because I'm a coward (because I think I'm far from it) -- but because it upsets me so much; because I feel it too deeply and have a lot of difficulty shrugging it off after as well.
