I'd have probably laughed my head off at myself, but I do understand your imbarrassment..

Those kind of happenings are the things that make you want to stay a Hermit..
Jappy, Honey, try not to dwell on the what ifs...it will drive you nuts. It was an honest mistake, that could have and has happened to anyone..

If you didn't have MS, you would be laughing you head off..
I can remember doing foggy stuff like that, even in my younger, foggy years. It's not always an MS thing. Having a foggy moment or day, is a normal thing and can have many causes, such as lack of sleep.
Don't be hard on yourself about this or I'll have to have AMN come over there and smack you..
