I caught Zack the other day doing circles round the tree stake in the back garden. Nothing has changed with the tree in over 1.5 years so I couldn't figure out what was so interesting.
Zack continued dancing round the tree for over 20 minutes!!!! It was quite comical really. I wished I had a video camera as it would have looked really funny to music.
Maybe the old pair of panty hose that have been tied to the tree since it was planted in 2010 were starting to smell??. I couldn't figure it out but Zack hasn't bothered with it since. Weird.
