[usr] I recently had a big argument with my sister. We both got very upset and angry at each other. [sys] Isn't that what sisters are for?  What were you guys upset about? [usr] I'm not so sure. We just had a discussion that heated and became an argument with tempers flying. [qst] [None] [bhv] [None]

I recently got very upset with my sister when said some very mean things to me. I let her know that she was out of line by yelling at her. I feel bad for both of us.
