My glasses have been too big since basically the day after I got them, and EVERY SINGLE WEEKEND since I've said "we need to stop in on Saturday to get these sized." But I never do. Because even though my glasses are absurdly loose, I always forget that they need to be sized until the very second that I lower my head (either sleepily or melodramatically) and they immediately fall right off my face. Then I tell myself to get them fixed, put them own and forget again.
I've done this three times in the past hour.
