You sat on your school's bleachers, watching your friend, Carlos, run laps around the track with a few other guys. Noticing the sweat glistening on his forehead, you get up from your seat and lean against the barrier, holding a water bottle. He notices your offer, and jogs over to you with a smile.

"Ah, thanks! I needed this." He pants as he takes the bottle, and you expect him to chug it seeing how sweaty he was. Once he opened it, he dumped the water all over himself with a satisfied sigh.
