OK, I'm sensory c5-t2. I live with people and I try to wait until people are done to use the kitchen but every time they come down. Now, cooking is risky for me, add distractions and people, a potential health threat to myself and them. Too many accidents that I gave up cooking for awhile. But I'm trying to get back into it and it's like they do not realize they are major threats to me. Even when I was not this way, I didn't like people in my kitchen because it's all about timing and you are doing multiple tasks. If I'm cooking, don't come in and cook with me or occupy space or clean dishes (I need access to water). Is it too much to ask for 30 minutes by myself? It's 10:32 PM here. I waited until they were done. How do I communicate this is a health threat to them an me?
Sounds like a community meeting is in order, Out. What you, and many other walking quads need, IS out o the ordinary and difficult for others to understand. You may have to explain it over and over. Can you make a floor sign, maybe steal one from a restroom and cover it with your own message? "Piso mojado" becomes "Falling risk! Do not disturb cook! Come back later." A sign would be good because it is both amusing and reminds people of something they will not remember otherwise.
It is not too much to ask that people leave you alone in kitchen, but it is too much to ask them to remember to do so. Out, after 15 years with me growing ever closer to deaf, I have to remind my SO many times per day to speak slowly. These are subconscious habits. A few people will remember- maybe 5%.
