Don't you let her get away with that!
You should have responded with something to the effect of "...at least I'm not hitting on your friends", which might be really inappropriate depending on her age so use your own discretion there.
Probably make her think twice about questioning how you spend your free time again

The folks here are not sad or pathetic (like the ones in the "lint that looks like politicians" collectors forums.) We're people who have harbored a dream since our childhoods, and now that we are adults, can use the knowledge and abilities that we have gained since then to make it a reality. More kids nowadays should have something like this to look forward to when they get to our age.
On another note, one of my 2 daughters and her husband are about to give me the ultimate joy/ death blow to my youth...a first grandchild. I'm only 40!! (I'm not old,I'm not old,I'm not old,I'm not old,I'm not old,I'm not old....)
