One summer afternoon when I was around six years old, the family was at my aunt and uncle's house for some sort of party. I was in the pool, and my dad and his cousins were watching me, making sure I didn't drown. As I was swimming, I wondered out loud if my uncle could buy a slide for his pool. My father, who I suppose was bored and possibly a little drunk, decided it would be fun to tell me there was a slide.
I swear, I looked for that slide for thirty minutes straight. And every time I asked where it was, someone would point to the opposite side of the pool and say, "It's right there!" until my dad decided to stop torturing me and told me there wasn't a slide.
For years, I thought that slide had disappeared off the face of the earth, and I was the only person who didn't get to see it before it "left"
