I was in my community shop yesterday afternoon and I noticed that the lady next to me was Deaf... I only did a Basic course in TSL (Trinidad Sign Language) but I still wanted to say something. But she looked so serious I was too scared to say anything in the case that i might offend her. The thing is I hardly meet Deaf people so I really want to be able to talk to the few I happen to bounce into.... can you give me some tips?
