Heah, it can be a hostile world for cyclists. We share a common interest. It seems this is a part of cycle ethics and almost always; either I or a cyclist passing me by asks, are you ok. It would be like abandoning a human out there in the desert, to cope with the wolves.
On a couple of ocassions, in my thousands of miles of riding, I ended up needing an extra tube. A fellow cyclist gave me one and would not accept money to cover its cost.
ps- I find it a wise idea to carry a 'tire patch.' Once got stuck when my tire got really "nailed." A tire patch could remedy this problem.
