This thread's a nice way of excluding the oldies xD
I haven't been excluded yet, so here's my deal. My parents have always been a great influence on me, for obvious reasons. They've been a part of my life since before I was even aware of it; they taught me the basics to life, and much much more. I guess I look up to them as role models, for their capability in dealing with three children at once. It's not an easy feat. I appreciate all that they've done for me, and so every decision I make largely depends on their opinion. That's not to say that I do everything they tell me to do, but it's still something I factor in when making decisions. I try to please them as much as I can, as a way of thanks for all that they've done for me. But like they say, you can't please everyone.
As for my peers, their opinions do matter to me, and so they do have a certain amount of influence on me, but for the most part, it's limited to trivial matters. It depends on which friend, but even still, I guess you could say that it's small in comparison to what my parents think. Having said that, my parents are pretty easy on me, and for that I'm grateful.
