In the Midwest of the US of A, we typically celebrate a high school graduation by opening up our houses, making a lot of food, and invite everyone who has been a part of our graduate's life. The grad gets a bunch of cards, money, and some gifts, and sometimes we have a fun party in the mix.
However, as we've talked to our friends and family who live in other parts of the country, they explained that grad parties are not common tradition in their area. Apparently it's just a midwest thing.
Is this true? If you're from another part of the country (or world), how does your community mark the graduation from high school?
