You, like most people, extend your personal preferences to all men (and even to all mankind in general). A lot of people like to receive as a gift what they want, rather than what will prove the love and attention of the donor. If you are asked what to give, it means they want to make you pleasant (truly pleasant, really what will bring you joy), rather than just self-affirming and showing yourself good and attentive. Will the filatelist enjoy a duplicate of the brand? And I’m not going to have a pleasant set of colors that I don’t need (I’m an artist). I would be more pleasant if they asked me what I needed, wrote the exact name of the manufacturer on the leaflet and even the exact list of the colors I needed and gave it. This is hidden under the question "What do you give?". And when you answer “Yes, you don’t need anything” – be prepared for what you will be understood literally. For example, people like me, because sometimes I respond in this way, and I don’t even think of being offended when I’m not given anything.
