Mother's Day, why not Friend's day?

You know, I get the whole Mother's day concept because personally my Mom is great. For the most part Mom's listen, are understanding, are willing to help out in anyway they can, they are there for you, they always provide a shoulder to cry on, and they brought us into this world, and they should have a special day dedicated to them, but..... what about friends, they stick around and they don't even HAVE to, now that is impressive!
