In Parshat Mekez we learn a very valuable skill and that is how to subliminal messages in order to get what you want. We learn from Yosaif how to  ask for what we want in a way in order to RECEIVE it! When asking for what you want from someone, they don't always necessarily want to give. A person can be in the Klipa and it makes it hard for them. To get what you want from them you must plant the idea as if it was their idea! It is different from when you ask God because God always wants to give.
