Pass It On

My co-worker comes into the stockroom with a spring in her step, singing a little tune, and she dances a couple steps down the aisle. 

"You're so happy, I love it!" I say, enthusiastically.

"I just had a really nice customer, and it made my day," she replies with a big smile.

"Makes me think that maybe I could effect somebody else's day positively, too, right?" I say.
