One day, an old man visited his wife’s grave as he did every week. As he sat there, a stranger lady appeared and knelt down beside him. The old man was puzzled at first, but then he noticed tears in the woman’s eyes. She whispered, “I’m sorry” before placing a bouquet of flowers on the gravestone. The old man was taken aback by her words, wondering what she could be sorry for. He watched as the woman walked away, leaving him with a sense of mystery and a newfound appreciation for the kindness of strangers.
