When I invited that former cashier at that grocery store to my comic book sale and she was so nice about it, I vowed to not punish her for being so nice to me. Instead, when it became apparent that she would not reciprocate in kind for my gesture in any way, I bailed. I think that was the right thing to do. Hey, it's not as if I expected the moon and six pence in return from her after I bailed, is it? My behavior helped me later on when it looked to me as if this former cashier was vying for some "free" attention in some weird way, and I could separate myself mentally and emotionally from her to the point where I could see where she and hers left off and I began. If that makes any sense.
