The other day on the bus a stranger wearing a baseball cap and sitting in the seat behind me tapped me of the shoulder and asked if I wanted to hear a vort. He told me in the name of The Novaminsker Rebbe the following. After it discusses returning a lost item it says you will go home and then you will return not look away from the lost item and will return it. But this is after you've already done the returning! His explanation was that it's saying that once you do this right thing in the future you won't be able to look away and will for sure return a last item when the issue arises.
It's nice when people on the bus tell me Torah.
