Where's my hug?!

I come home from work and usually say to the kids, "where's my hug?" They humor me and come running. Tyler is usually really energetic and exited to see us anyway, even if it's first thing in the morning or just when he hasn't seen us around in the house for a while. But the other day I came home and Tyler stood across the room with his arms wide open and said "where's my hug?" I went running. He didn't stop at that---took a few steps back and did it again.
