Yes. The last 5 or 6 years I've celebrated my birthday alone. What I have sometimes done for my birthday is
take a trip to Las Vegas by myself, book a room in a decent hotel, catch a couple of shows, enjoy the buffets, and just chill and relax. If I waited for friends and family to call me up and invite me somewhere for my birthday, I'd have a very long wait. This is why I just say "Screw them, I'm not waiting around, I'll go do my own thing, by myself."
