I don't feel quite so invisible on FB. I take the time to craft my posts, and end up looking like a fairly "normal" person, and at the same time, I'm able to post stuff that goes almost as deep as I want to go with people who are on there. I get to have my say about something, and I've taken the time to think it through, and people don't interrupt you as easily when you've already typed out what you have to say. Plus, their ambiguous body language isn't nearly so distracting when I can't see their reactions to my posts.
IRL, however, I usually feel invisible when I don't want to be, and conspicuous when I'd rather disappear. If I'm standing in line somewhere, it's not uncommon for someone to walk right past me in line without even noticing I exist. Happened just the other day at the car dealership where I was waiting my turn to check out, had waited for about 3 people in front of me where they took forever, then finally I was the next person in line, the TWO people behind the counter both ignored me, then this big guy walks in and straight up to the counter and they immediately ask him what they can do to help him.
And then there are times where I just know everyone is aware of how odd I look or how strange I'm acting. I work very hard to dress in such a way that I'm not unpleasant to look at (but not provocative), because I don't want to offend anyone with looking frumpy or unkempt or slutty. But then I attract unwanted attention from a certain type of male, and other women turn their noses up at me because I don't act like them. And at church where the building is full of safer people...everyone does their weekly duty to come up and say hey and insist on a hug. I get that they're trying, and just doing what they believe is the nice and "right" thing to do. But almost no one takes the time to figure out what I actually might want from the interaction. Not that I can blame them, because honestly, I don't even know what that might be. I just know that a hug and asking "how are you doing?" doesn't work.
Sorry for the long post...just venting a little.
