You tend these graves, nearly hidden by trees, sand, and rocks. The candles remain lit, and always there are signs you've been by. I've yet to meet you, though I pass this way often.
I see only the dog, and I leave it food and water, but it shows no signs of ill-use. Surely you care for it as you honor the dead over which it keeps watch.
May the gods bless your tender care of the departed.
