A friend who has known me for many years wants to buy me a mobile phone. I like it very much, but I don't know how to reply. How to answer politely?

A friend I have known for many years wants to buy you a mobile phone. This must be said first. Being able to say this to your face means. No matter what kind of friend you are, you are very important in his heart, and so is she. The economy is still good. At least it should be much better than you financially, so. Emotionally. She is willing to go as a matter of buying you a mobile phone. And he also has conditions. So I think this is a good thing. But you like it in your heart. But I don't know how to answer. That depends on you. Where do you put her in your heart? If you have a good relationship, that's good. Very close relationship. Or ... he pursues you to a certain extent, and you have to accept it. Degree, then you should. You can say yes directly or thank him politely.
