Delving or searching too deeply into something may cause you trouble. Don't push boundaries further than you need to, do only what is required.
dont poke your sly nose into peoples lives
it means you dont go outside the boundaries ordained for you other wise you will only take loss and nothing.
It means that even if curiosity is something natural and typical to all human being, one should not go beyong the limits and looks for trouble. Otherwise, it'll turn to be dangerous or harmful, especially when it comes to personal things; for as someone said "The right to swing my fist ends where the other man’s nose begins". So, take it forgranted that people who are too curious will, sooner or later, have problems.
it means that you must not be curious than the limit because this might be harmful or not good for you
