With calmness

You force a gulp in an attempt to stay calm and composed. The last thing you want to do is act all nervous and abnormal around her... especially because of her wearing a swimsuit underneath. A smile appears on your face. "Hey Chris! I came here to relax and have a fun time at the pool. Swimming could beat the heat... unless the heat beats me first."

Christina chuckles a little. You weren't trying to be funny per se, but more so lighten the atmosphere. "It could be worse. You could be stuck in a classroom with a broken AC." She lets out another small laugh. "Man, that'd really suck."
