when it's time to leave the gym

Sometimes it's difficult to know how hard you should push yourself. Sometimes that decision is made for you.

Last week I was running on the treadmill, and I was doing okay at minute 16. I could go on, but I didn't really feel like it. I usually make goals for myself ("One more minute!"), and I was wondering what my new goal would be. But before I could do it, something made up my mind for me.

The sweat from the guy next to me splashed on my leg.

That's when I knew it was time to leave the gym.

Gross.
