Grocery Shopping.

Have you ever had a moment when, all of a sudden, you realize that something you've been doing your entire life is really, truly strange? I had one of these moments yesterday, when I realized that I talk to myself out loud in the grocery store.
It's true! I realized yesterday as I was buying taco supplies for my small group that I was speaking at an audible volume, looking for tomatoes. Not loud enough to disturb the other shoppers, mind you, but loud enough that if someone didn't want to go through the mental process of finding the best value on any given product, they could just stand next to me and copy my answer after I've figured it out. It went something like this. "Okay, now I need tomatoes. Lettuce, cucumber, zucchini, squash... there they are. Tomatoes. Oh. These are organic. Probably better, but more expensive. Hm... where are the other tomatoes? These look good. Is this the best price? Yep. Okay, one tomato. Is that it? No, I still need cheese."
The horrible thing is that I think I have always done this, and I'm not sure that I can stop. Will you still be my friend if I talk to myself in the grocery store?
