Random info: the name of the story had to change because I'd removed the description of the ant swarm in order to achieve the 50-word target. I think this shorter version has a very different feel to the original story... the playful "friend" character has transformed into quite a menacing figure.
Here's the text, just in case the link isn't working.
My friend is a foot taller than me. That makes him the leader.
"They taste like butter," he says, showing me ants emerging from their nest. "Try one."
I grasp an ant as it takes its first view of daylight. I watch it struggle, small, helpless and lost in indecision.
