Awkward Situations

I find myself in awkward situations now and again. People don't often listen to what I have to say, so I just stopped saying things. Nevertheless, I find myself in situations where people actually ask me to say things, and then they STILL ignore them. Then they wonder why I don't talk, or why I bring books or game systems and spend time by myself playing or reading. What do you expect when you talk about things I know nothing about or ignore what I say when I decide to plug in?!
