Not so much a random act of kindness, but a good deed nonetheless, so it kind of fits: I was out canoeing with my sister this weekend, and when we went for a break at a resting point we saw a lonely dog standing by the edge of the water looking at us curiously, a dachshund to be precise. There was no owner in sight, so after pulling up the canoe we approached it. There were some other boats out on the water, so we thought it might have been left on land as the owner went out, but to be safe we called the number on its collar. Turned out the owner lived on the other side of the lake - about 10 miles away, and he'd been worrying about her. So we waited with her for 15 minutes while he crossed the lake in his row boat to pick her up!
