Amen.
All the time, too. I had a fellow just today tell me I needed a tech to come to my house to fix my cable. He told me to turn cbl off and hit menu two times. Because it would not work he was sure that I didn't understand. Sigh. I lost my patience and told him that Deaf doesn't mean DUMB. He said -" Huh "!! All cause my sweet hubby "forgot" that I needed captions. grrr. Hahaha, we all have those "deaf moments", I guess.
I also now have folks ask where I am from. It's cause I speak sort of flat now. I don't always hear myself as well as I used to. My young terp friend had to insist to a store clerk that I was not foreign. geee. People!
