Years ago my therapist said i could send her a friend request on facebook if i wanted. She asked me, she said she would have just sent me one, but she asked because maybe i would have a problem with seeing her family pictures and personal things on there, and didnt want to trigger me.
It was fine with me, so we have been facebook friends for a few years now. She had already looked up my page,but it didnt bother me because tons of people see my page anyway.
