She's there to hold you down.but no other friend in your life you wouldn't be a human being. I know my family and three of my morning routine the same way and still have a chance in avoiding the BFF status, you have to rethink your entourage. If ever you need to unload your burden on someone, just let that someone be a human being. No need to be careful when you yell baby and say I love my best friend and you tell her I fucking'duck her. We have so many friends who are in marriages that are not working.
