I went hiking last week with the guy I'm dating. It was only our second date, and I thought I would try to match his physical fitness by suggesting a "moderate" hike, 3 miles total out and back. I'd never done the hike before but it was suggested by one of my coworkers and he said it was "fine". So we start out and it's just climbing and climbing and climbing and more climbing, which he is breezing through. I felt like I was on the stair stepper to he**. I tired quickly and had to throw in the towel. I was so embarrassed that I couldn't complete the hike, but he was such a good sport. I just wanted a couple of flat areas to catch my breath, but none to be found. Note to self: don't trust coworkers
