blanket forts and painted pictures

Cody and Avery (my younger brother and my neighbour-who-is-basically-my-adopted-little-sister)decided to build a fort yesterday. They kicked me off the couch and took every last cushion (and a couple of the dining room chairs, too) and busied themselves in the living room for, I dunno...maybe twenty minutes, building.
When Mom and I were called to survey their creation, they shot at us with Nerf guns (which is why I only have three pictures. I took a bullet to the eye when I tried to get a few shots of the inside. It actually hurt quite a lot.)

And then, somehow, I got roped into having a battle with them, ducking around the corners and trying to aim between the cushions. (they let me inside after a while, but guys, it's sad. I'm way too big for forts now. My head served as the main pillar, because I was taller than the chairs they were using to prop the roof up.)

And then later, they painted. I joined in, because although I don't have much any artistic skill, I love paintbrushes. I love the soft bristles, the way they swoop across the paper, how the paint gradually runs out until you're only leaving a faint, feathery trail...
I never have any idea what to paint, so I usually just do shapes, swirling and pretending to be some fantastic artist who whips their brush across the canvas and creates a masterpiece.

How do you spend your summer afternoons?
