What has been the most meaningful birthday gift you have ever received so far? Or the most expensive one?

The most expensive gift I have ever received in my life was 20 dollars in cash. The most meaningful one happened during my student years. One day, while I was walking alone, I ran into my university friends. One of them turned to the others and asked me, “Is it your birthday today?” I said yes. They said “Okay” and left. After a while, they called me and said, “Come here, we need you.” When I went, I saw that they had prepared a surprise for me at a café. They celebrated my birthday there. It was truly an unforgettable and very meaningful day for me. What about you? What was the most expensive gift you have received? And which birthday of yours is the most memorable?
