"Your getting faster", from a cat 3 guy that I beat in a practice crit in a sprint who never compliments.
"What the h#@l" after I just bridged a 100 yard gap at 33 MPH to catch the lead pack in a crit
"Your bike is nicer than mine" from my LBS mechanic who has a 16 pound tcr (now a 14.5 pound tcr advanced)
"You are definitly an A Rider", a club member after my first ever itt.
I could go on but my all time favorite... from a certain race promoter we will not mention
"You are now a bike racer!" after completing a cat 5 crit with the lead pack.
