Where’s the lie?

I couldn’t help but notice the lack of “quotation marks”

I took a computer programming class for a semester in high school and was a Computer Science major for a month in college, but that’s the closest thing I’ve got to anything resembling a technical background.

I walked on the treadmill today. It was nice. No pressure to go fast or do any prescribed workout. I put in my earbuds, had a video playing off to the side, and went at my own speed. First time I’d done that kind of thing in a long while, and it was nice. Got a whole mile in. I don’t know if that’s the appeal exercising has for everyone else, but that’s it for me.

Even more importantly, why is Lenny?
