[Blindtlk] Questions concerning how people look like

[hmp]

TO WHOM IT MAY CONCERN:

     I'm very sure everyone in this mailing list is blind. Maybe 
some of you are not. And well, I have a curiosity, or a question, 
that maybe you can answer for me and if it is not that 
intimidating:
     As you know, sighted people tend to look at each other's 
face, or perhaps most of the body movements and the hands, while 
they're talking to each other. For example, when somebody is 
talking and facing another person, that person faces that other 
person, and he or she can look at the person's face. In addition, 
this does not happen when they are talking only; the person can 
just look at that other person, E.G. a boy says "hello" to a girl 
perhaps, and he looks at her because she is pretty (or she 
perhaps isn't) and he looks at her smile and he knows what she 
looks like. He can maybe remember her just through all those 
details of her. Furthermore, there are more case-scenarios out 
there that are very similar to this one.
     While sighted people do this, as far as blind people are 
concerned, is there any way a blind person can do the same things 
just like the sighted? Can a blind person tell how someone looks 
like by some technique or some information? If I want to know how 
someone looks like, what can I do? Sometimes I think that 
probably by touching faces I can get a general detail of what 
he/she is like, but some people may see this as an offensive 
thing. I have just a little bit of vision (mostly out of the 
corner of my right eye), but I cannot see well enough to see 
these things. I can only see very close objects or people. But 
anyways, if, for example, I meet a nice girl and she says hello 
to me, and she carries out a conversation with me. How can I get 
the physical description of her? How do I know if she is just 
smiling without laughing? How do I know what her hair looks like? 
maybe she has a pointy nose, a big/small mouth, and probably 
really all straight and white teeth! How can I know these things? 
I could perhaps ask her, "What do you look like?" but I've had 
bad experiences asking that question, although some people are 
kind and they tell me. Again, I don't see any bad thing by 
touching people's faces, however, I'm not sure if I should 
totally do it because of an offense or just being disrespectful.
     I am asking this question just for curiosity, and I'd like 
to see what you think about this. Any feedback and comments about 
this topic are welcome. I'd like to find out what other blind 
people have done to accomplish well this situation.

Thank you and have a very lucky day!
