Can I say one thing?
I'm deaf. I don't know if you know if the deaf community is a very small world. So there are very tight ethics with our interpreters.
If I already knew X before she became an interpreter, she can still be my friend and I can still go to her place as a friend. However, if I met Y after she qualified as an interpreter, and interpreted for me somewhere quite confidential (medical or legal), it's not ethical to date or socialise outside of that relationship. It's to protect the client.
Because it's such a small world, we do run into each other in intimate social gatherings (weddings, birthday parties, funerals, baby showers, etc.) we do chat, but I do not say where the interpreter interpreted for me, and they are not allowed to say if they interpreted for me, or where. This code of conduct and ethics is to protect us deaf people as clients and our privacy. The reason we run into interpreters is they may have close family or grew up with deaf people in the deaf community, or have deaf parents.
So they have to pass a rigorous program to qualify, and there is a board of ethics we can complain to and have their qualifications revoked if they cross boundaries.
