Idealistic Friendship vs Realistic Friendship

Friendship.
Many people talk of true friendship
but the question is are they talking realistic or ideally?
To me a friend is someone who is there, maybe not always but you know that if you ever needed them they would come through for you however small or big the scenario may be. They might live far or they might live down the street. It makes no difference. To a lot of people the ideal friend will never hurt you, will always be there etc etc. Well realistically all friends (because they are human beings, and human beings are fallible to error) will eventually make a mistake. And there is nothing wrong with that, everyone makes mistakes, in fact it's a mistake that once you and a friend get past makes you stronger. If your asking a friend to be perfect, then in my eyes you are not only living in a dream world but you are probably not worth their time. Because friendship is not lopsided, things don't go one way and one way only. A friendship is also about balance. Sometimes you might do this one day because your friend loves to do it some days you might get to do what you love. Just because you want a perfect friend doesn't mean they can't have one! And since nobody is perfect it's impossible to have a perfect friendship. Well.. Ideal friendship.. let's just say that. Because perfect is what you see it to be. To me perfect is like i was saying a friend that will overall be a Positive influence on you, always be there etc etc. if you look at the positives/negatives they will all be positives except for the occasional negatives when they, like everyone else in the world, slip. But to someone else a perfect friendship is someone who is ideal and the truth is that can never happen. There is not one person out there who is never going to make a mistake so the ideal friendship can never exist. For those of you who have had a friend mess up before you have to realize there is no one that is perfect and that everyone makes mistakes, so if they are still worth your time (still positive after that 1 negative) then keep them as a friend. Think of friendship as a math problem or something along the lines of that. They are always adding because they are such good friends +1...+1..+1.. and so on. Well say they are at +30. Is a single -1 going to tear your friendship apart? NO! your still at +29! and if they keep things that way they will reach +59 before they make another mistake! ohhh so what -1 brings you to +58. So what? People must understand that the number is the impact they have not only on your life but your perspective! They are the ones that either get you in trouble or get you into something productive! They are the ones that make you view your life, and others, with regret, or no regrets! They ultimately sway your pessimistic/optimistic view upon things. And in my opinion if someone has raised my life 30 points and slips by 1 point then so be it! I embrace the mistake because i know 30 positives will grow out of that one negative. Nobody needs a lot of friends but everyone needs true friends.
