First, happy birthday in advance. The emphasis on decade birthdays doesn't resonate with me, but my 50th ended up being special because I got my first kick scooter. This is a life-changing event for an urban-dweller, and at the time (8 years ago) it was unusual for adults to use kick scooters, so the birthday was special accidentally.

I hope you end up with a celebration that suits you perfectly. I recommend being completely self-indulgent for every birthday.
