Well, that was brilliant.

I drove to the grocery store, got there, and realized that my snack-holder (purse) was still at home.

Crap.

Drove home, grabbed it, drove back to the grocery. Thought, "you know, it might be wise to just leave a credit card hidden in the car for times such as these." Reached into my snack-holder.

Discovered that my wallet had fallen out at home.

/facepalm

I gave up at that point. Obviously there is a higher power at work here that does not want me fetching groceries tonight.
