Ok. So yea. I did the exact same thing with my son a couple weeks ago. Bounce houses and slides. Epic. I think we each had the exact same amount of fun.
I put my 2 year old on the bouncy castle and she didn't like it at the beginning so I was like, ohh let me come and take you off this thing... then I got to take her down this massive slide, so much fun.
In all seriousness, yes, this is why I'm the coolest aunt ever. "Happy Thanksgiving kids! Let's go to the indoor mini golf place and knock each other off of pedestals!"
