When the kids and I got to the park today, there were no other people on the playground, but there was: an uneaten apple; a baby bottle full three-quarters full of thick, purplish-pink liquid; three stuffed animals, lying together on a platform at the end of a tunnel; one measuring cup that appeared to have been called into use as a shovel; one fuzzy blue lovey blanket; one fringed hair tie, placed on the lovey blanket; and one piece of sidewalk chalk.

So either a playground full of people was suddenly called up to heaven or abducted by aliens, or else a toddler brought a lot of things to the park and then melted down and was carried home, leaving all the belongings behind.

Or am I missing some other obvious explanation?
