If someone says "I don't know how you remember all those words" I hear "oh dear, that was SO long and tedious".
If someone says "That was interesting, where do you find your songs?" I hear "Hmmm, that wasn't really what I'd call a folk song was it?".
Though if I'm brave enough to tell them my doubts they're (usually) shocked and reasure me it was good.

Observing other conversations it seems people who are always polished and mega competent don't receive particularly more compliments than the average performers.
