I feel a little weird and a little guilty even though I did that as the second half of a short car-related errand I needed to do tonight -- fill up while I could still use a 40¢ discount I had at a Fred Meyer fuel station only a few blocks further -- with stopping at the mercado adding several car lengths to my total trip. NOT MUCH, in other words.
I try not to drive too much, or too unnecessarily, is the thing.
OK, Chris, make sure you keep not doing stuff you'd honestly feel guilty about!
