Not so fast with that fork, buddy — let’s have some plate boundaries

I was out to lunch, and I asked if my friend would like to try some of my salad. Before the question was finished, his fork slid across the table and speared a healthy pile of field greens.

There was bacon involved, so his enthusiasm was understandable. Still, I was a bit skeeved out by his fork entering my plate’s airspace. So can we set some ground rules for sharing meals?
