If I go grocery shopping while I'm particularly depressed, I buy less food than I actually need, and it's a guarantee that some of what I buy is bizarre stuff I picked up because why not it doesn't matter anyway.

Sometimes it's pretty funny the next day when I realize that all I have are the ingredients for a Charlie Brown Thanksgiving.
I'm this type: I don't mind grocery shopping. I don't like leaving the house and driving to and from the grocery store. But once I get to the car, I go do the shopping without too much further dislike for the chore, and once I've bought the groceries, I gotta drive home.
