The source? An entire day with my Sweeties at the Museum of Technology. We arrived when it opened and left when it closed. The two big attractions that lured us there were electric cars you can drive and a workshop where you could program Lego robots to drive through a course on "Mars."
These were both successes with my (now 9-year-old) Sweeties but the biggest hit of the day was the Wii dancing game. It took some convincing to get them to try ("But I don't want to dance Auntie Bella!") but once they did, that's all they wanted to do! Such a good form of exercise too. And something we could share as I love to dance and love games...and love the Sweeties too of course. You can see a sample of their dancing in this video clip:
To my delight, one Sweetie slept over, complete with breakfast, a piano recital, two readings of The Sound of Music pop-up book (including all the songs) and a long listening to music on YouTube while snuggling on the bed session.
People, I tell you, life is good!
