Do I look old in this?

Okay, so here's the deal: Over the years, some people have remarked to me that I look and/or act older than I actually am, which of course makes absolutely no logical sense whatsoever considering that there are people older than me who act like teenagers, and people who are my age or younger who have half a head full of white hair (the other half being grey hairs of varying shades). Nevertheless, this hasn't stopped people from being surprised when I tell them my real age, which may or may not be a good thing depending on how you look at it. Of course, since I'm a guy, it's not so bad since (as some have pointed out to me) a guy who looks mature is generally seen in a better light than a woman who looks old ^_^"

That being said, however, I gotta say that it's still kinda disturbing to be having dinner with my family the other day, only to have my sister suddenly grab my head and start staring at my hair while telling me not to move. I mean, I was like "WHAT THE HELL, WOMAN????" until I got my answer a few minutes later, when she announced to the table "HE'S GOT WHITE HAIR!!" and pointed at the offending strand of hair (yes, just ONE strand) before twisting my head around to illustrate her point ("Look, look!").

Normally, I'd put this down as yet another item on my list of "10564 (and counting) reasons why I hate the army", but until today I've yet to see any evidence of this singular ivory strand so I'm going to assume it was the lighting of the eatery we happened to be in at the time. Frankly speaking, I'm more surprised at the fact that I didn't just reach over and smack her upside of the head for that little stunt; still, I've got plenty of other ways of annoying the hell out of her, so it's all just as well I guess ^_^
