Looking at the world through lawyer-colored glasses

This is a point I've been wanting to make for a long time and I wasn't sure how to get it across. I think I'll try to do it in bits and pieces.

I was walking around outside at Easton last night. I looked down at my feet as I walked and saw a grating. Suddenly I began to imagine how young a child would have to be for their feet to be small enough to fit into the grating, and what the worst possible injury they could experience would be if they got caught, and how much money the mall could be sued for. I should say, if it's not clear, that I'm not at all pleased with myself for thinking this. But...what does it mean?
