When I was in high school I was hanging out with my friends one day and the topic of 18th birthdays came up (officially being an adult and all that). One of my friends mentioned that he would get a large sum of money for his birthday (I'm talking about 10k euros or more). The others didn't seem to be shocked by this and all said they'd get about the same. I just sort of nodded and avoided the topic because I knew I'd get nothing like that.

This one is not as life changing or important as other examples in the thread, but it always stuck with me because of how casual they talked about it.

Not that I'd change anything if I could, I love my parents.
