People are becoming Facebook friends with old classmates, long lost cousins and the neighbour across the street. Teens especially seem to have a tendency to add almost everyone to their friends list that asks. So, if one of their teachers should send them a friend request, they’re likely to accept it. If they randomly came across a teacher’s profile on Facebook, they might also send a friend request too, without thinking much about it. A teacher, however, should give the situation some consideration.
