That is funny - I had to bring Izzy's tricycle in the house this winter too! Whenever we went somewhere she'd see it in the garage and start yelling "Bike, I want bike!!!" so of course I obliged! :)
Ha, ha!! Glad to hear I'm not the only softie! What is funny is he will drive it in the family room and park it in front of the big screen tv. Then everyone is mad and trying to get him to move it. He will just sit in it and watch tv!
