Funny, I've worn glasses my whole life, never worn contacts, but being farsighted, don't use them unless I'm working on the computer or doing copious reading. My kids didn't even know I had them until I came home from work one day with them.
Now, Nub's got glasses, and it looks weird to me. I always knew that at least some of my kids would wear glasses, but nine years later I'm a bit unprepared.
Sigh. Whose vanity is worse -- theirs or mine? I think we all know the answer.
