Contagious behavior

Everyday I ride a shuttle from a parking lot into my work.  Typically it's the same core group of people depending on who's late or early.  Since I sit at the front of the shuttle, it's become my habit after getting to work and trekking to the door from the drop site to swipe my badge to open the secure door and then just hold it open and let others go inside first.  Most people smile and say thanks, but there are two in particular who now, after months of this, try to take the door or encourage me to go ahead if them.  I smile and say, "it's ok, it's a good way to start the day by being nice to others!"  Occasionally one of them will GRAB the door and push me in, in a silly way, and we laugh and then I open the second door and usher them ahead of me. Ha!

Today, we got off the shuttle, the core four of us, and I am not joking here, the same two ladies RAN (in their dressy shoes and coats and carrying their pocketbooks and lunch sacs!) ahead to open the door! Funniest thing I've ever seen and I was laughing as I walked thru the door ahead of them.  But as we all went our separate ways, one sweet lady said, "it's contagious behavior, being nice to people..."

Yes, yes it is, and I intend to spread that stuff everywhere!
