I was out on a ride today, and got a flat right at my turnaround point. I stopped to take a bite of a granola bar, and somehow got a flat. It seems to happen a lot. Is the only way to beat this to never stop when I'm out riding? Sigh, anyway...

There were at least 10 other cyclists who passed by on the road as I was fixing my flat on the sidewalk. Only 2 bothered to ask if I was okay. The others just leaned deeper on their aerobars and continued focusing hard on...not looking at me as I waved? Keep in mind, I'm 16.

Is it normal for 80% of cyclists to not ask if someone fixing a flat needs help? Do you slow down and ask the person if they need anything? Why or why not?
