looking out for number

My input on whether or not you should interfere with another persons life,is that a person you should let them look out for themselves and not have tell them what to do,or fight battles for them. Because it's their live and not yours,so you really have no reason to come into their lives and boss them around. I can understand though if your an over-protective person,but its up to them if they want you to be i their life.
