Self Motivation at the Gym?!

Options
So. When I'm on the treadmill I always talk to myself in my head. I'm like, "When you're wearing that bikini in July you're not going to remember how crappy the last 5 minutes of running was, you're going to just know how hot you are." or "It's just 3 minutes, you are so much stronger than 3 minutes." Just things like that.

Well, I always THINK I'm saying it in my head. But, today there was a guy on the treadmill next to me and he was like, "Uhm, excuse me?" And I was really confused because I had my headphones on. So, I took them out and looked at him because I thought he was asking me a question or something. ANd he was like, "You said something, and I didn't quite hear it?"

LOL! I was so freakin embarrassed! I've probably been talking out loud to myself for two months and didn't even notice until today. I told him I was just having a conversation with myself and he laughed and I kept running. But, it was still so funny!

Has this happened to anybody else? :)
