Funny, Here I have only seen one DEAF couple and there is at least one person in every store here that knows ASL. We went to the city just this past week, stopped at subway for dinner and I walked over to McD for my son a Happy Meal. I was ordering from a young black girl and I assume she noticed I couldnt hear and started signing to me ( asked if I was Deaf ) I signed back yes and it all took over from there. There are alot of Hearing folks that know ASL and it really surprised me as I never knew there were so many around us...
Not surprising. An increasing number of ASL classes are being provided in K-12 schools and college contributes to that.
