First off, I know a jeep is not a mustachian vehicle to own, but I bought it before learning the mustachian way and I don't drive it very much.
Anyway, I recently bought a house that is a 5 minute walk from my work, yay! Thursday evening I drove to my parents house 13 miles away to visit (I don't like to bike very far in the dark). I stayed the night there and drove to work in the morning. Then I forgot about my jeep, walked home for lunch, back to work, then walked home at the end of the day. Didn't remember that my jeep was still at work till this morning.
