One step behind one step ahead of you always getting over looked , you treat me like a stranger but I've been there the whole time ,you just never looked ! I see it all I hear you cry I'm There when you sleep I'm around when you fuss and fight I'm big I'm strong ! I'm willing and mighty I'm loving and caring , you know this but your still hiding I won't ever leave you actually I need you but you need me too without me there is no you! What am I ?
