That would make my day regardless of how it was going up until then. Sadly I rarely see other cyclists, and the only people I've ever had riding alongside me were a college riding team that passed me like I was stopped, I've passed newbie commuters on MTBs a few times, I totally smoked a guy who I think was probably about 70 years old last week and an older lady who had just blown a stoplight and was really snotty about it.
