note:

NOTE: when riding a bicycle there is a measure of courtesy that revolves in our brains
we give more space and decrease speed for different types of people
old people are given more space and passed with less speed
women and children/pregnant women are also given greater courtesy
small children and pets are passed with caution and anticipation
always expecting the unexpected
runners and other cyclists are passed with respect
people with headphones and cell phones are ignored just as they are ignoring the world around them
