Forty is quickly approaching, you guys! I refuse to call it old, lol! It’s just extra experienced, haha!
One of my favorite things about turning forty, besides finally not caring what anyone thinks, is the excuse to throw a genuinely great party. There was a movie marathon and way too much cake.
We even had a tiny contest for who brought the best appetizer. Nobody remembers who won, but the leftovers were gone by morning!
Don’t fret if you have zero party planning experience. I used to struggle putting together anything fancier than a grocery store cake. Now I plan a whole theme every single year.
