Couple on the 10

I took the Line 10 subway home from work on Monday. It wasn’t too crowded when I boarded (from the second stop), but it fill-up later on with folks traveling home. I saw this couple standing not too far from me. She seemed pretty tired, and he was holding most of her weight in his left arm (I think his right was holding onto a rail). I thought there was something terribly romantic about it.
