"Behind closed doors, most people aren't who they appear in front of them."
I think I know what you're trying to say here... this is projection. You assume most people are like you. Good to know.
secondly, if violence and abuse is the only world you really know, it stands to reason your child has grown up in this world as well (keeping the circle going)... what type of violent abuse have you perpetrated upon your lovely child?
PS: you're fat, over weight at best... And you know this, man.
