Last dawn I went into "really stupid mode". Woke up in the middle of the night with my eyes itching a lot. I went to bathroom and grabbed the acetone instead of collyrium (by mistake, not because I wanted to join some jack ass episode).
Well, I woke up myself, cats, boyfriend and probably some neighbors, screaming >.o
As I'm typing this you will probably realize I'm not blind :P but it wasn't a very nice experience, and it quickly turned "really stupid mode" off :P (no need to say it was dumb, I feel dumb already).
