We went to Sky High, a big trampoline place, to end the holidays well. It was not very busy so only 3 courts were open. The main/normal court, a court you dive into foam and the dodge ball one.
Towards the end my son told me he had to do the dodge ball. The girls weren't interested. The little one run of to the foam court and I was watching with my oldest. She noticed that although there plenty of girls, it was boys-only here! The purpose of the game was beyond both of us... but brother came out happy. Conclusion: it must be a boys thing!
