Oh, and as we used to sing when I was a kid: 'May you never take birth again, may you never take birth again, may you never take birth again, happy birthday to you!' (refering to liberation from samsara of course!)
We went to a buffet (we didn't book it), and the staff found out it was my birthday since they're on good terms with the family. They then came out with a piece of cake and singing Happy Birthday, in front of like, everyone, much to my sis' shock.
