I don't get it...am I alone...I am asked at family get togethers and parties to play "their " piano...

Last Sunday my wife had a family reunion (folks I never met)..and yes they had a piano (Wurlitzer)...naturally you are asked to play...you are a musician..RIGHT!!..

What do you guys do that avoid the piano...do you keep that s950 in the car......or that old accordion in the back seat
