Avatar/signature vs. true personality?

Have you been treated different because of your avatar or your signature? Like I've talked to members and a lot of times they'll think I'm much younger because of something else a in my signature or what picture I put in my avatar. Like a long time ago I said something about my Mom calling me a brat LOL I'm well over 50 years old and she's over 70 LOL but when I talk to people they think I'm 19 LOL because of something I mentioned on my signature. Or like that current picture I have on my avatar it's as probably some of the old-timers can recognize a picture from an old Mopar movie. Case in point for myself when I first joined the forum Triple-R had a Beavis or butthead in his Avatar and I instantly liked him LOL
