I am amazed that people often ignore situations around them. It's so easy to just ask if someone needs help. Even if you think you might not be able to be of assistance, sometimes just having an extra set of hands is needed.

A few weeks ago I was riding with both of my kids with the trail-a-bike and burly. We were on a long, steep hill and I dropped a chain. I think 5-7 cyclists rode right past us. I'm an experienced rider, fixing a dropped chain is no biggie. But I was surprised that no one offered to help being that I obviously had a mechanical issue and two small children with me.
