Gosh, I hate it when people who should know better come over to my house wearing their smelly stuff. My nurse came over and set off a major asthma attack. It took about 2 hours to get my breathing back under control. The best I can figure it is either her shampoo or her fabric softener. Both were smelly. She has been here before and didn't have a problem, but this time we sure did. Not exactly sure what it was or just the combination of the two. It really drives me nuts to know that people sometimes just don't think. MCS really sucks.
