I will avoid eye contact if I'm in a bitchy mood, having a bad hair day or just too busy, running late and don't want to be bothered....
Not becuz of my deafness tho'....as just today, I was leaving the Groomers with my Dog, and this lady stopped me to admire my doggie "Anita"...and once she found out I was deaf, she signed to me...so the convo was real nice!...
I've no need to avoid people because of my deafness. Most of us want the hearing to accommodate us...and some do just that, others have no idea of how to do that and it's understandable (as for me it is). Just a friendly wave of Hi/Hello...and how are you should suffice...
