So you know that annoying guy who elbows into the circle as the conversation winds down and excitedly demands to know what you're talking about?
That's me. And I've got an opinion on it, too. You're talking about nice guys, aren't you?
As previously noted, till 16 I was a large, large kid. And, as so many of us heavy ones are, I was also a nice guy. Unlike all the bastards who got girls, I knew I'd treat them to flowers and chocolate, candy and consideration. Didn't help much. But, again following stereotype, I latched onto a hot friend and became her good buddy. As happens, I developed a huge crush on her. As happens, it was not reciprocated. As happens, I was crushed.
Best thing that ever happened to me. It's why I lost my weight.
After weight loss, though, I realized I still didn't know how to talk to girls, what to do when they approached me, etc. I had kinda thrown myself into the deep end. So I studied it. I watched who had sexual success and who didn't, I tried to find common characteristics, I tried out various personas during Friday nights at the mall. It was all very scientifically done. If I had paid half as much attention to high school, my final GPA might have broke 2.2. But though my GPA never rose, my mating studies were a success. And what I found, in the end, is that nice guys have no problems. Insecure guys do.
