1 Well that's not what I expected

On my way home I saw this man on the side of the road and he asked for a lift... of course I said yes being the kind man I am and he thanked me greatly. Once I got him to where he needed to go he gave me a hug but on my back it felt like he pinched me, so I politley asked what happened but he didn't know what I was on about. So I forgot about it, until the next morning...
