I've got a riddle for you:
A mute man walked into a convenience store. He wanted to buy a toothbrush. He managed to successfully convey this to the store owner by mimicking brushing his teeth. He got his toothbrush. Then a deaf man walked into the store. He wanted to buy a pair of sunglasses. How did he get the owner to understand what he wanted to buy?
Its funny, but many deaf people can't really talk. They find it extremely difficult because they have never heard anyone speak and they can't hear their own voice (if they were born deaf)
No. People don't really look angry when they yawn and there are no vibrations coming from them like there are when they scream. If they yawn in middle of conversation, they are not screaming. It would not make sense.
