Why do sign language interpreters look so animated?

I have been around a few deaf ladies. I found signing to be engrossing and sexy!
 
Yeah Bloomberg's interpreter is awesome! I get a kick out of watching her do her thing.
 
I used to see the deaf students at George Brown college talking in the cafeteria...they were very expressive and animated. I always wanted to fuck one of them, but never got the chance. I did however play a concert at a deaf school and a girl in the crowd gave me the fuck sign, but once again I never capitalized on that opportunity either. Doh!
