Hmmm. That's kind of a pickle... While I often don't have a lot of confidence in my own opinions, I have a degree of "Not so fast!"-ness when people try to pressure me into doing things.
For example, there was this party I went to when I was about thirteen, I think... My mother had promised me no one would force me to dance before dropping me off, but, as soon as I got into the room, the DJ announced someone had arrived and the guests tried to literally drag me to the dance floor. I resisted and fled their clutches. End result: I spent the whole night in a lonely corner, staring outside the window, until it was time to go home.
Bottom line: I can be a bit doormattish at times, but I'm not always passive. You bite me too hard, I can bite back. Or at least plant a bear trap in your pillow.
...Or, most likely, just sulk and feel bitter.
