Dunno' what you do when you're happy but I roll 'n roll 'n groom 'n roll. My hooman says: "Spirit's happy -- he's rollin'. It's true! Why am I so happy? It's cause I found my fav bag, that's why. My hooman takes it to her classes. I love givin' it the sniff-all-over test as soon as she brings it home -- it has the most intriguing scents. Love this bag!
