A pacer is a buddy of one of the other team, who tried to sneak him in, but when caught, he's a guy who gets to practice for free...
I have never used a pacer, but if the opposing team asks if I care it's usually not a big deal. And frankly, I don't think TWOHAND834 thought it was a huge deal either, just wanted to know other opinions on the subject.
Sometimes we FEEL that something that happened was a little weird, and want to know if those feelings are justified or not. A forum like this can get the whole range of responses because we come from the whole range of backgrounds, etc.
My wife likes to watch Dr. Phil, while I go crazy trying to get through 15 minutes of it. Is she right? Am I wrong? For the sake of our marriage, yes and yes. But the real answer is neither, we're just different.
There will always be those you offer "advice" trying to be funny, and others who insult, and a few who actually think before they start typing. Deep down we're probably all pretty good guys, just different.
