I have quite a few experiences, but will share this one because it's most recent and funny. A few nights ago hubby and I went out to a nice restaurant/bar to have some beer and appetizers. While we were sitting at the bar sharing jokes and funny stories, a JW couple (who I knew quite well years ago) came in and sat behind us. I didn't notice them, the bar was pretty full and I was focused on hubby. In fact, I never did notice them until they were done with their meal and the JW husband got up, came over, and leaned over the bar where I was sitting to get the attention of the bartender in order to hand him the bill. Funny thing is - he didn't need to do that - at this restaurant/bar you just leave your $$ on the table with your bill and the waitress picks it up. As soon as he (the JW husband) had my attention, then he turned on the "I'm being obvious and shunning you" look and behavior. So - I just turned back around and kept visiting my husband.
The guy came over AGAIN and leaned over the bar where I was sitting (for some other useless reason), then when he had my attention, tried the "I'm shubbing you again" look. I thought it was hillarious! After all - aren't they supposed to be AVOIDING me? Evidentially, they can't avoid me unless I KNOW they are avoiding me. I got a good laugh over that one - how neurotic! At least it offered me some fun and cheap entertainment.
