When you say "introduce" yourself... Why?

By social conventions, it is polite to present oneself. When one socializes, dissemblance is an integral part of success. And yet people are always telling others to "be themselves." And yet, in truth, if we were to act as ourselves, many of us would never introduce ourselves.

In fact, in this post, I've been trying to impress you. Apparently.

Anyways, I'm new to philosophy and to forums in general. A firm believer in chivalry (despite its apparent death) and grammar (that is to say, I believe all people should strive toward superior communication - not that everyone should have perfect grammar.) And I have a problem with putting my foot in my mouth. I guess most of my posts will be about education, religion, sexuality, gender roles, and social conventions, since that's what I'm interested.

Oh right. You can call me Andy.
