How vain is too vain?

I hate bad pictures of myself. Tonight I had to pose for a head shot at my gym. I swore I saw him chuckle after it was snapped. I couldn’t help but thinking it was goofy which I sloughed off with a “pretty dorky shot huh”? At which he only smiled. Now I’m convinced there’s a completely goofy head-shot which will pop up on the screen at the health club every time I scan in. In a previous health club I was able to glance at my photo and noticed I didn’t like it and got them to retake it. It won’t keep me up at night or anything but things like this are like a grain of sand in my shoe. Any identification with this or am I just completely whacked?
