I am in the states. I am a sign language interpreter that was trained in the religion at early age and signing on all assemblies and meetings w/tons of bible studies.
YES ,we had a list of where to go for deaf people and I know the Interpreters working in the schools, when able to underhandedly get where the kids lived, wow!!! all of a sudden interpreters of theirs, from school would show up at their doors. It would be very very hard to shake your own school interpreter from visiting you since you knew you would be seeing them in a day or two in the front of your classroom. That is one of the many ways people would somehow pop up at a persons door and somehow started signing, probably they say just coincidence that the angels led them. Even finding out that kids had deaf parents some how round a bout their address would come be found out and people some how knowing how to sign would show their faces at these doors!!! Innocent???? Yea right!!!!!
