meetings

I was just in a meeting and I am working on designing some part of the board, and when my name was mentioned for designing it, someone smirked as if they did not believe that I can do it. It just makes me so mad and frustrated when people do that. Another person asked me a question, and I did not know the answer and they kind of made a mean facial expression and laughed weirdly. I so don't like meetings, and I have to go to these meetings once a week. I already have two meetings a week. I try to avoid the meetings but then someone reminds me to go to the meeting, and I just want to forget the meeting. What's the point? I just usually sit there and say anything because the other people want to do more of the talking.
