I thought all families did this, but David's didn't, so maybe it's not as universal as I thought. I have great memories of my Nana and I sword-fighting through the house with empty wrapping paper tubes and laughing until we fell over. We gathered up our tubes and today it was ON. It was an epic Jedi/Ninja/Knight battle for the ages. Vivian was more interested in using her tube as a telescope, but she did manage to get a few good whacks in. Adeline and David battled it out until their swords were shredded. SO much laughing and so many great faces from Adeline - even though she's laughing she takes it pretty seriously!
