Express Yourself!

Ok, so I'm on this expression kick and by that I mean I've become very interested in how and why people express themselves in certain ways. I seem to express myself the most online (especially emotionally)! I guess I feel a certain sense of security behind a computer screen that leads me to be more honest whether it's chatting (IM) or just posting my thoughts digitally in blog or micro blog form.

Well I have recently noticed the large amount of self expression that can be found on bathroom walls. It usually contains crude jokes (which is probably the most enjoyable place for them) but can also include anything from political ideas to general bullying to sexual expression/experimentation. I have even taking to recording the bathroom "wall posts" on my flickr account. I love when people utilize a new or unusual medium to express themselves. I mean really, ask yourself what else is there to do in a public bathroom stall (other than the obvious)?

It really makes me wonder, because a lot of people write things like invitations to party's and phone numbers. Are these people trying to get a dialogue going. And what about the people who use a bathroom wall to just express themselves? Is a response welcomed (even a negative response?) or do you feel that people who comment on your stall art encroachment on your personal expression space?

I really don't know, but I think this age old method of self expression is very interesting! Check out what I've seen so far.
