Contemplating retinas and mascara

I contemplate more living alone. Maybe I always contemplate, I just speak it. Anyway, I was putting on mascara and trying to remember how many days since I had done so. Then I remembered I can't see all that well. I thought of people who really can't see and how they must do their eye make-up, and I wondered if I walk around with noticeably gobby mascara. I was trying to put it on smoothly and remember what Oprah's make up guy said about doing the bottom lashes when I slipped and make a big black spot on the side of my nose. Now I am wondering about old people putting on make up. Not too good. Think about people with obviously dyed red and black hair, maybe they don't know it doesn't look so good not because they have bad taste; maybe it's bad vision.
