Why?

I was blog hopping tonight, and wondered why I feel the need to have a picture in every post?  Occasionally I'll post pictureless, but generally not.  Perhaps it's because I don't feel like I'm witty.  Perhaps I don't feel like I can't put together a cohesive thought.  Perhaps because I think my life isn't that interesting.  I'm not sure the reason, but I'm trying to work through it.
