Call me Sally..
Could be she is right. Riding is dangerous. ya' know.. "it's not if you go down it's when"... etc.
May be she didn't sign on to be an early widow, or for her kids to have to visit their dad in the hospital.
It may have nothing to do with turning in your Man-card, but more with respect to your partners opinion and the fact that she may know you better then you think.
I am of the age now where I can almost keep to the speed limit, but there was a time when the throttle might as well have been an on/off switch..Needless to say I ride a whole lot more now.
