Random story:
A couple of days after Christmas, a neighbor that I don't know (he lives one street over) got his car stuck on a large patch of ice outside of my house. I heard tires spinning for a couple of minutes before I peeked out of the window. I got dressed and grabbed a bag of rock salt to give his tires some traction. He got about half-way off the patch, and then got stuck again. I noticed that another neighbor had thrown out their Christmas tree, and I recalled reading a post by Carl/jackknife about how he helped a stranded motorist by cutting small branches from a nearby bush to use for tire traction. (I believe, not surprisingly, that he used his Peanut.) It was dark out and frigid cold, and I didn't want to take off my gloves to use a knife, so I just used arm power to de-limb the tree. The added traction did the trick, along with some pushing. The gentleman came back on foot a few minutes later and knocked on my door. He introduced himself, and I reciprocated. By looks, I'm guessing he might be long retired (I'm in my mid-30s). He thanked me and tried to slip me a $20. I politely declined, and after a few minutes of chatting, we parted company. The feeling you get from helping people in need, even with something simple, is it's own reward.
