Did you ever think you were going blind?

So when we go away it is usually a family affair, therefore lots of people in little/few rooms. We are currently a family of 14, used to be 16 until 2 recent divorces, but anyway, there we all are in 2 hotel rooms/suites. On Sunday morning I got up and took my shower, now I am totally blind w/out my contacts, I can see blurry shapes and colors, but that's about it, so after my shower I put in my contacts, and I couldn't see out of my right eye, so I took it out, cleaned it and put it back in, still couldn't see, so I tried to pop it and I had noticed it felt thinner, I thought to myself, boy when they get old to they disinegrate? So I kept going and then went into the other room, well I could see nothing, all blurry...major pet peeve of mine...can't stand to not be able to see. So I went back in the bathroom, took it out again, cleaned it and put it back in, still nothing.....man...what the heck....then it happened, I looked up on the sink and saw another contact case.....I was putting my sister's contacts in my eyes........needless to say, I am A LOT more blind than she is....few crisis averted, heaven forbid I have to wear glasses all day.
