I have one professor that always forgets to turn the mic on, so once I determine class has started and he isn't just talking to random students in the class, I make a gesture pointing to my ear and shake my head.
What is it with people and coming up from behind? No matter how many times this happens, I still get startled when I turn around and they are right there. This happens all the time at work, especially when a patron is on the public computer and they try to get my attention when my back is to them, depending on the air conditioner or heating system and other noise factors, I sometimes hear them, most of the time I don't.
While it isn't the most complicated, it's easy for them to ignore, I mean, why should they care, the problem isn't them, it's us. I wonder if normal hearing people think deaf people are a-holes when they don't reply to them when they aren't in visual range of them? I can sometimes hear someone that I don't see, but not understand them, so that's my alert, but if I couldn't hear at all, and someone spoke to me and I didn't see them, I'm sure many people would assume I was an a-hole rather than make any other logical connection.
