I understand you don't know. Common sense would dictate no nail polish or perfume for most people but some people just don't think of it.

I have a latex allergy which I could die from (hence I carry 2 double epi pens). Less than 1% of the population suffers from this allergy. My mother has it - I watched her flat line 3 times in the hospital. Perhaps made me a bit more paranoid. I've only gone into anaphalatic shock once after being exposed to latex balloons. But one time is enough. It's scary. I feel for those with nut allergies that severe. My mother had anaphalatic shock on an airplane because cleaners had been on with latex gloves. I don't expect people to watch out for me - I have to watch out for me. I have extreme allergies. It's life. I could have been dealt a worse hand. My daughter and step daughter understand why they can't get balloons at the restaurants/grocery store/dept. store/birthday parties/etc. I am well prepared. People do not understand the severity of the allergy and think I overreact - that's okay. I don't expect people to. I do my part to think ahead. I just want people to do their part with common sense and courtesy.

Again, I don't live in a bubble and don't expect the world from people. But spraying pefume and putting on polish on a plane
