A million years ago I worked in the deli dept of a grocery store. My entire shift consisted of scooping up potato salad and slicing bologna. Guess what?
When I'd get home I'd be too tired to cook but the thought of throwing a sandwich together made me want to hurl. Why? Because I had been exposed to it all day long.
That's all it is, babe. You just need downtime is all. I feel the same way about errands. But once I'm out and about I seem to be able to shake the persistent, "I hate people" syndrome I've been suffering from.
Of course that comes to a screeching halt once I have to drive again but that's a story for a different day.
