I really don't know why I don't ask more. It might be because I feel like that obliges me to engage, and I don't always feel like engaging? Maybe I don't want to get into arguments with people, and often the things I'm thinking about will probably provoke certain people to respond in an argumentative fashion?
LOL You sound so much like me. (I ask a lot of questions and sometimes I just cannot engage due to lack of time or worse, if I do answer, I might get PB'd. But that never really stops me.
