Remembered another one:
I was at a gathering with about 25 people--church related (heh).
A friend of mine was going to nurse her son. It was crowded and she asked if she could sit next to me.
She put a cover on, but I could still see everything--nipple and all.
She caught me looking. I said I was sorry but she said "well, better you than anyone else here."
I kept looking and she stared at me while I stared at her. She didn't make any effort to cover up more and never told me to look away.
I week later we were at another church gathering. She sat by me again. She let me stare again. I asked her if people see her nursing all the time and she said I was the only person besides her husband and mother to have seen anything as far as she was aware.
This happened three times total. I haven't seen her since.
I told my wife about it, and even though she was there all three times, she thinks I am making it up. My wife said, "There is no way [so-and-so] would let you see anything; she must not have realized it." I figure it's safe to leave it at that than to argue with her about it.
