A few months ago I was in New Orleans. I took with me a phone, an extra shirt, 15m of rope and headphones. I was walking around in the morning and found a guy sleeping on the ground. He looked well kept and just partied too hard. I gave him a bottle of water and chilled with him for a bit. Then we started walking around and he spotted some friends that were towing a car with jumper cables but the end had broke so they were tying it again. I offered my rope to help and the guys looked confused and I explained that it’s always useful to have it. So they towed the car home. I hung out and had some beers and we swapped stories then went on a date with one of their friends.
So that’s why you always have rope.
