Stay Out Of My Bubble

Attention close talkers, and personal space invaders: If I step back from you when you are talking to me, it's because you are standing uncomfortably close to me. The last thing you should do is step closer, and if it happens a third time I can't even guess why you don't get the hint but, I can't step back again or else I'm going to hurt your feelings. Also please don't stand an inch behind me in line. There's all the room in the world for you to stand so I politely wonder if you could stand anywhere else besides on my ass.
