Wow, what I find most amazing about your disastrous ride is that your friend wasn't carrying her own inhaler! That is a pretty critical item. She shouldn't be relying on someone else to carry it, and then getting huffy when you didn't all stay together. EACH person on a ride needs to carry items to be self-sufficient (water, patch kit, spare tube, pump, tools, money, spare clothing such as arm & leg warmers, emergency food, emergency meds like inhalers, etc). No one should be relying on someone else to carry things for them. That is not fair to the other person(s).
