She has noticed what you like, admire, and read, and brings you gifts that reflect what she has observed. The quality of her gift shows the level of her perception about what you like.
If she is rich, she may buy you expensive presents. If she is not, she may send cards, books, or poems. If she is not rich and she sends a Porsche or a pricey suit, she’s got some problems.
Have the grownup conversation with her about how you don’t like gifts she can’t afford. That would be a very loving thing to do.
