Cool! I could do something super to commemorate it, but I just want to share an experience from yesterday.
We were driving around and Daisy was peeking out the front passenger window. This kind of rough looking fellow was walking in the cold, smoking a cigarette, and he crossed in the crosswalk in front of our car and saw Daisy peering out at him. He just stared at her, then a big grin broke across his face. When he passed over to my side, he mouthed "That is one cute dog." and he was still grinning so big. He didn't seem like the type of person to appreciate a silly fluffy dog, but I think it really made his morning.
