I'm oralized and a lot of strangers are surprised when I tell them I'm hearing impaired if I missed something and ask them to repeat something.
It is very annoying to me when people raise their voices too much. Jeeebus, I hate that. When people speak up TOO much, I say to them, "there's no need to speak louder, it's the clarity that counts, not the volume, my hearing aids already increase the volume." Most of them turn bright red and apologize.
I accept their apology graciously and tell them if they have any questions, to feel free to ask me no matter how dumb they might think the question is. You'd be pleasantly surprised at how many people of take you up on this if you "give them permission" to ask the questions they might be too afraid to ask!
If someone tries to whisper into my ears, I tell them that I'm pretty good at reading lips and to try standing in front of me. Bingo, problem solved.
I get much of the same "dumb" questions y'all get, but I've found that more often than not, it's ignorance, not stupidity. There's a huge difference between the two.
Remember that they don't teach people in school about hearing loss, so guess how they learn? They ask questions. Who better to ask than the deaf/hoh?
In my opinion attitude is everything when dealing with people's questions about your condition. Lots of people of normal hearing have very poor social skills and make rude comments/assumptions when in actuality they meant to ask a question, but they don't know how.
Soooo, every time someone has a question for me, I look at it as an opportunity to educate them about the deaf/hoh.
But if they are really and truly stupid assholes, I just make fun of them. It's really easy -- look for a physical imperfection of theirs and hammer away! Once you get enough people laughing at them, they usually just go away.
