best

I have found the real definition of best friend:

Someone you can live with and not be annoyed by the fact that they leave globs of toothpaste in the sink after brushing their teeth and they bring some kind of stomach virus into the house so that everyone under the roof acquires the virus and their shoes are everywhere except for the closet and when they make the bed, they don't fold the comforter and sheet down in that way that you like but instead tuck everything under the pillows. But they also wake up at your son's first cry and play with him for an hour or three so you can get an hour or three extra minutes of sleep. They also wake up early to surprise you by cleaning and organizing the house that you've neglected because you have three weddings to edit and threw up for two days straight thanks to that pesky virus and you're also having a going away party for one of your girlfriends. They bring you dinner and take you to brunch and arrive with blessed surprise latte's at all hours of the day. You can spend minutes that turn to hours that turn to days on days with them and the annoyances don't add up like little ticks in your mind until you need a free minute or you'll scream.

That's how you know you've found your best friend, your soul mate, your love. So stop looking, be content and take adventures and forget the people who aren't this and never will be.
