My daughter arrived today and my grandson and I walked to our closest Taco Bell to meet her for lunch. All that fresh air and exercise wore me down. We walked home, all three of us. This is probably more taxing walking than walking the Mall. By the time we got home three hours had passed. I ended up taking a nap after we got home. My daughter is currently visiting friends and my grandson is snoring in the living room. The fresh air caught up with him as well. My feet, knees, and right shoulder are reminding me that I am getting older. The nap didn't help with the aches.
