Mark and I went to the aquarium this morning. Mark enjoyed looking at the fish and sharks. I let him out of the stroller and he pushed the stroller around. There was a bench next to one of the fish tanks that was perfect for Mark to stand on and watch the fish in the tank. He also enjoyed walking back and forth on the bench. By the time we got to the stingrays, Mark showed signs of being tired. He took a nap on the way home.
