Bryan has a train set from his childhood. I never knew he owned one until the other day we came across one that really intrigued Holly while we were on a Santa Train - he mentioned then he had one. The next day he brought it out and spent some time sprucing it up and getting it working again. Then Holly & he played with it most of the afternoon. I am not if he had more fun 'tinkering' with it or playing with it. Either way they had a lot of fun and it was neat he was able to share another of his own childhood toys with her.
