I visited a friend years ago, who answered the door looking like he got the worst end of a bar brawl the night before. Before I could comment, he quickly explained he had eye surgery; Lids that got in the way. I don't notice it in myself yet, but when I look at pictures of myself, I see I've got one eye that is drooping slightly, as if the muscles of the lid have given up. I may need the operation some day. Just don't have it on the day before your first date with a woman you want to impress.
