When the hubs and I go grocery shopping together, we usually get a cart and spend much more than if I go by myself. I'm sure that's typical for most couples. We do our "big" grocery shopping together, but there are a lot of times throughout the week that one of us will stop on the way home to pick up a few more items.
Tonight, I stopped on the way home from work (in the pouring rain!!) to get a few things we don't keep on hand (bacon, half and half, celery and onion) for baked potato soup tomorrow. When I shop, I always get a basket and work my bicep carrying it around. I'm proud and ashamed to say that after tonight's trot around the store, my left bicep was a little shakey on the drive home.
