Who are you?!!!...

I think that it's being friendly to look at someone and say how are you. I don't have to know a person to speak. People are really friendly where I am. Southern hospitality. I could be in a long line in Walmart waiting. Someone may say what's up and stike a conversation and we will talk instead of being bored waiting in a long time.

This again sounds like it can typically be South_Africa. Here all the black people, ask you how you are, straight after greeting you, even if you are a complete stranger. In their language and culture it is polite to do so. Here is a example in isiZulu. Sawubona (Hello) Kunjani (how are you) Ngiphila (I'm fine) Unjani wena (and how are you) Ngiphila (I'm fine as well) People struggle in the beginning to get use to it because to us it is a bit arrogant,or presumptuous, to them it is good manners

That happened to me recently. I am legally blind, so I have to ask people a lot. A lady approached me who was vaguely familliar, but we met in a location where I was not used to seeing her, so I really oculdn't think of who she was. I asked her and she kept saying I recognized her voice. If I had recognized her voice then I would have known who she was!! She just wouldn't accept the fact that I didn't know who she was.
