When my husband and I were dating we were not even allowed in the front room of his mother's house even though she was in the next room watching television and the door was open. I felt insulted that they thought so little of us.
We had an old brother in our congregation that looked like Dumbledore from Harry Potter and he said if he saw a sister walking to the meeting in the pouring rain and she was soaked to the skin he would not give her a lift as he didn't want anyone thinking there was something going on. Fat chance!
