<human>: I'm a very non-confrontational person and was taught growing up to have great manners and be respectful of others.  When I was 19 I went with my boyfriend at the time to a movie that had been released a few weeks earlier.  I went to the movie weeks after the release date in hopes that there wouldn't be many people in the theater so that I could get the seating I liked best.  Sure enough there were only a few other couples in the theater and I got the perfect seating I wanted.

About 5 minutes after the movie started, two guys came in and sat in the seats right in front of me even though the whole theater was practically empty.  I had my feet resting up on the back of the chair in front of me as one of the guys sat in it.  He politely turned around and asked me if I would put my feet down.  I snapped quicker than I could have ever imagined, raised my voice, and said that I wasn't going to move my goddamn feet and he would just have to deal with it.  While still angered about the situation I started to calm down a few minutes later and was in utter shock that I reacted in that way instead of my usual non-confrontational self.  I slowly put my feet down and watched the remainder of the movie confused by my own behavior.

<bot>: Raised my voice and acted like a child when asked to put my feet down off of a chair in a movie theater.
