We were told this as well by the Poly concierge (DD was giving away a gently used princess dress to another family we knew only through TGM) and I thought it was a really good lesson for DD to know that doing something good was meaningful. She gave her 2nd pin away to a girl in a family that let us share the rope with them at DHS rope drop, so DD could see. DS got one later in the week at Mousegears for picking up Mr. PotatoHead parts (I think it was Mr. P) that were strewn all over the floor and putting them away.
I was disappointed to see later in the week, though, a monorail CM with one on her lanyard that someone had obviously traded her for! Just sort of spoiled the specialness for me, but DD didn't pick up on it.
