I don't mind taps on the shoulder. I guess I have been around deafies enough that doesn't bother me.
The thing I have to work at is the hugging. I am originally a CT Yankee, and hugging was reserved for close family. Now I live in the South, and deafies and hearies both are huggers. I always respond warmly to hugs (not to offend), but I feel awkward about initiating hugs.
