My parents are the same. I keep my nook with me at all times as it has IP-relay and that is my official number to be reached at, but when I'm at work, he calls there on the phone and he knows I can't hear anything on that, but he calls anyway.
I deal with being the exception all the time and yes, it is extremely irritating. I'm still considering just signing that I'm deaf, so people will leave me alone, that has to be a lot less irritating to deal with. Like on Saturday, I was at work and a lady came in and started talking and I couldn't hear a single sound she made, so I just told her right out that I couldn't hear anything she had said and politely asked her to speak up and she just kept talking too low for me to hear, so I had to get a coworker to deal with her.
Once I get my hearing aids soon, I'm wondering if people see it, will the get the hint or will human stupidity continue to ensue?
The main thing I hope for is being able to hear without the mic/ ear buds thing, so many times I wanted to leave at the end of or during class and was unable because I needed the microphone part back from the professor. I feel chained by that, and in the classroom I fear group activities because I only have one mic and the professor uses that, so I either miss what he/she says or miss everything the group says.
