...My Weird Locker Decoration Choice...

So I got this cool locker mirror for my combination lock last week. Everyone was like, 'Wow! That's a great idea!' But then today at lunch, I caught myself looking in the mirror while putting away my books and realized that...I look kinda awkward doing it? Like, people probably think I'm too vain or something....I don't know why I did it though...it just seemed like a good idea at the time....
