You're always mature in your discussions, and I have found you to very often be the voice of reason. You are very calm, and I really appreciate that. To the extent that an anonymous forum allows for, I consider you a friend. Please don't change, I like you just the way you are!

I have misjudged you in the past quite a bit, but you're growing on me. I like you now, even if we disagree at times. Your concern for me and my family is touching, and I wish I had the time to hang around here more. If we ever meet, I'll buy you lunch, although the same holds true for anyone here I like. I think of you (in a platonic way, of course) when I'm not on the forums. I wish I knew you better, you seem like you'd make a great friend offline.

You have been a hugely positive impact on my life. I know you're going through a rough time right now, but things are looking up for you! Don't let yourself feel like you don't matter, the truth is, you still have your family, your friends, and myself. And yes, you do have friends. We just met with one today!
Life isn't a popularity contest, and I've found that the more friends you have, the more likely you get negative attention. It's better to stick with a few good friends and be able to rely on them when you need to than gather them by the hundreds and not know a one that will stand by you when it counts.
