Having spent over a decade in an orphanage, I remember none of us got the privileges to cut a cake on their birthday. Most of us forgot our birthdays by default. I always almost forgot my birthday until level 300.
I was overjoyed cutting our 5th-anniversary cake with the August Borns at BASCO. So whenever you get the chance to celebrate your birthday, try and have it in an orphanage so the kids can have the cake cutting feeling. You do not necessarily have to go with tonnes of donations… the cake and the champagne are enough
