When I first put this together, I thought, “This is a long, self-indulgent video of my daughter.” Thankfully, I realized that hosting long, self-indulgent videos of people’s kids is what YouTube is there for. At least 35% of it, anyway.
There are also pets in this video, which covers another 40% at least. Speaking of which, around the 3:05 mark, you can see Abigail’s expression change as she comes up with what she thinks is a devious plan. I predict this is something that will cause us lots of trouble in the future.
