We all do that & I'm pretty sure we can't control it. A couple of people got sort of angry when I changed my profile pic & said I actually look a lot like the guy in it. lol I still haven't managed to convince anyone that he's sad & tired, not arrogant & homicidal, btw.
I know for a fact that his supposedly threatening mug got me in trouble on more than one occasion, mostly with women. Everyone liked me much better when I was Mr. I'm a Loser Baby So Why Don't You Kill Me with big blue eyes & rainbowish stuff on his face, so I decided to do the stupid thing & not make other members think I have a baby face.
* Why am I posting this after saying I'm leaving the forum & risking getting called a lying attention whore? Because SS withdrawal is a bitch.
