Deaf Culture and tidbits
In hearing culture, one would typically see rows of seats in a classroom, where students sit facing forward, wearing horse blinders, err, sorry. Understandably, it's space-wise.
On the other hand, in Deaf culture, deaf students usually sit in a horseshoe shape, leaving their blinders, err again sorry, where they can see each other. Eye contact is part of communication in our culture.
