That gets pissed when people "ghost out" on you during a ride? My GF did this three fucking times today and I about came unglued! Two of the times, there was some justification, although I still cautioned her that she needs to somehow let me know if she is stopping.
Anyone that has ridden for any amount of time knows the feeling you get in the pit of your gut when you check your mirror and someone you care about is missing...
I turned around and went back to find her looking at some car for sale... I pulled a football coach maneuver, grabbed her chin guard and unloaded. If she does it again, we are done riding together, PERIOD!
