A person’s birthday is the one day of the year where it’s totally ok to gloat as people shower you with their affections throughout the day. It’s the one day where it’s ok to want to feel a little special.
Even Siri wants to make you feel special. If you tell Siri, “It’s my birthday,” she’ll start singing a sprited version of “Happy Birthday” before remembering that, oh crap, that song is copyrighted. Better luck next year.
