My co-worker is extremely nosy. I don't want to be mean, but how can I hint at him that he's annoying.
He will walk into my closet and just look at all of my things and glance nosily at all of my personal papers at my desk. He also copies every single thing I do. If I change the layout in my office, he will change his that very same day. If I purchase something for my desk, he will make the same purchase. If my boss gives me something helpful or something just out of kindness, he gets jealous (and makes it known he is jealous) or physically takes it out of my office for his own use. If I restock office supplies from the storage room, he will come into my room and restock his supplies with my supplies I just restocked (leaving me with no stock at all)!
