When I looked around, I noticed there were balloons and a big banner that said, "Happy Birthday, Ana!". It turned out to be a surprise party for one of his friends. The kids started inviting me to join them, and although I hesitated at first, I accepted and ended up playing with them for hours. It was an unexpected and very fun day.

Academic Knowledge and Real-World Application
