I'm going to make this short because I'm still at the gym.

I was doing my warmup walk before jogging on the treadmill when this super fine HB8 gets on the treadmill RIGHT BESIDE MINE, and there are like six to choose from on this particular line of treadmills. I look over, perk up, and smile at her like I would any girl I think is attractive. She returned with a slight smirk/smile of her before beginning her cardio session.

The entire 15 minutes or so that I ran my mind kept drawing a blank as to how to open with her. I couldn't think of anything and I was acting nervous, and I'm never like that towards girls anymore--thanks to you guys.

I finished my run, hopped off the treadmill, and went on my way to where I am now--sitting in the locker room feeling like a little bitch writing this.

TL;DR HB8 on treadmill beside me. Bitched out. Suggestions?
