The oak at the edge of the park is not where you expected your afternoon to go. Something large and round is wedged between the upper branches - and it's a person. A very puffy, very mortified person, gripping bark with both hands and trying not to drift any higher. She says the helium tank at her party setup malfunctioned. She says she tried to stop it. She says a lot of things very quickly, in the tone of someone who needs you to know this is NOT her fault. The branches are too high to climb easily. She's too buoyant to simply pull down. And the wind is picking up. Somebody has to figure this out - and right now, that somebody is you.
