Former Texan,
Grooming is such a shallow measure or reason for fitting in or not fitting in. You are a decent guy. I learned a long time ago that people's outward appearances do not even give an acccurate clue as what they are really like on the inside. I grew up on an island and some of my best friends were poor, unkept souls. They were picked on in school because they were poor and didn't wear nice clothes and were considered ugly. These kids were and are still my best friends.
One of these guys had a speech impediment, so he really was picked on. Fortunately one of our teachers spent time with him and encouraged him through school. He is now the president of a major multi million dollar construction group. Imagine that, poor, ugly guy with that can't talk plain!
The boss on my first job was a young, handsome, preppy type guy. Drove a nice a car, impeccably dressed, very popular. He liked me and wanted to be my friend. I bought into this slick dude line, hook, and sinker. He ended up raping me a few months later. I learned the hard way to trust my instincts, not outward appearances.
You seem to be a good guy. Like your 12 year old self for what he was, not what he looked like. Recognize the ones who picked on you or didn't like you because of the way you kept yourself up, for the shallow ignorant, egotistical beings that they are. I assure you their life will always be shallow unless they change. At some point, they will age and become ugly. They may even lose their money, but it won't matter...money has never bought happiness, just things and superficial friends.
One of the things about this site I like is that you get to meet each other and have no idea what anyone looks like. You develop friendships on merit, not looks. I don't know if I'm talking to a George Clooney or a Woddy Allen. Don't care, either!
YOU have substance. YOU are worth whole lot more than I think you realize, and it has nothing to do with grooming. Love your 12 year old self. Only God and you know exactly what you were living through then.
Take care Tex, and if you ever want, send me a PM. I always respond.
