put one's nose in
put (one's) nose in(to) (something)
To involve oneself in an intrusive or nosy manner into something that is not one's business or responsibility. I wish my neighbors would quit putting their noses in our business and just leave us alone! Don't put your nose into your brother's affairs—he can manage well enough on his own.
