I notice when deaf peeps always say "hey" and they dont have to finger spell of names.. I am aware that they are getting their attention. Have u seen "hey" or tap shoulder..
Well yea...same thing goes for in hearing culture. Let's say u meet another person at the store and u engage in interesting conversation..eventually, introductions are in order.
Same thing goes for deaf people or in deaf culture. Of course, we would want to know your name after chatting with u. However, dont go around interrupting people's conversations to say "Hi, my name is ...."
