Many happy returns

The setup: My suitcase is packed; I'm ready for the weekend. Bosslady sees suitcase and comments on its nice color.

Me: Thanks, I got it for high school graduation from my parents.
Bossguy: I got a typewriter. Shows how old I am!
Bosslady: ...I got a cow.
Me: A cow?
Bosslady: Yep, and every year she had a calf, and every year my parents sold the calf for four or five hundred dollars. I paid for all of my college and seminary books with my cow money.

What did you get for your high school graduation?
