I am a super quiet person. I will respond to you if you talk to me but I seldom start a conversation. It is because I don't have any ideas to express or there is no chance for me to talk (everyone is speaking, and I have no gap to talk). There is an activity coming on next Friday. I am really interested in it, but I don't know if I should join it as I am really quiet and I don't know how others will think about me if I don't talk a lot, especially the activity is only for 15 people. I am scared that they think I waste the opportunity as I don't talk.
