Tent.

My sister and her friend convinced me to build a tent for them, out of blankets. I chose to build it around the table on our back porch. I figured it would be up until the girls got hot and needed to go in the pool. I was right. And they got hot fast. I had strategically placed one of the tent's "bedrooms" in the sun. The blankets heated up fast, and the girls just had to get out of there. I joined them in the pool. My dad deconstructed their mansion.

I've better than I have in a while. My attitude has seriously gone up. I've finally gotten into the "eh, I don't care" mindset. Life is good!
