I don't have an older brother. But Seth comes pretty damn close. I've known him since high school when we sat next to each other in band. He went off to college and I followed him 2 years later (well, one and a half, if you want to be technical).
Over the years, he shared his love of laughing (and Monty Python), his class-skipping techniques, his wisdom, and his hugs with me. We've seen each other through major breakups. We've left each other countless voicemail messages. And almost 2 years ago, I was honored to officiate his wedding ceremony.
Today is Seth's birthday. If I lived closer to him, I would celebrate with him, but since I don't, I'm using the internet to send my good wishes (and a virtual cake).
Happy Birthday Seth!
