I have an ordinary friend who never mentioned my birthday, but asked me for her birthday present on my birthday. How can I refuse her?

Leave her alone. As a good friend, you don't need a gift. Besides, she didn't give it to you. Why should she give it to her? Is it for her own benefit to be a friend like her? So try to avoid him, otherwise, the conditions will become more and more excessive, but as for gifts, we are not short of money, right? But the truth is to be told. Tell her what you think, and maybe we will have a good relationship everywhere in the future!
