Lending a hand
Whenever I see a cyclist on the side of the road I always ask "are you OK?" and the answer is "no", i stop to assist.
So i'm at the end of a ride and just put the bike in the garage and see a woman walking her bike in the street. I ask "are you OK?" and she said "no".
She has a old low end mountain style bike and says one of the brakes is broken. I have her bring it to the garage and see it's just the cable retainer is bent and I simple squeeze with pliers is all that's needed. Then I see the tires need air and a myriad of other small issues. I ask her how far she's going and she said to the local bike shop, so I put air in her tires so she could ride the mile to the store. I told her to tell the owners I say hello since I've known them for years.
So you never know when the opportunity to help a fellow cyclist will happen.
