Old Couple

I was in a jeepney sitting at the far end. Sitting in front of me were an old man and a woman.I thought they were a couple and that was proven when got off the jeepney. When the old man got off first, she took the hand of the old woman, whom I presumed his wife, and assited her. Isn't it cute? I was expecting that the old man would just leave the old woman, but I was touched when he guided her.
Now, I'm thinking how good could that be- couples who stick together until their old
age. It's such an amazing story.
