Sweet insight on the train

Just witnessed a very sweet moment on the train:
A short woman could not reach the top rail to leave her bag. No strong man around, but a very kind old man offered to help. Unfortunately the bag was too heavy for him and could not lift it to the rail, so the woman stepped in and lifted what she could and bang the bag was up there!
I thought this was a very sweet moment and showed me how creative cooperation is the way to go...
