My brother Björn and Karin, who I got to know because she dated one of Björn's best friends 20 years ago. LOVE THESE TWO.
Karin lives pretty close to me. People mistake us for each other all the time - a short, brown haired, energetic woman with three kids in tow, married to an avid runner.
If Karin and I had a kid together she would look exactly like Tina Fey. We consider Tina our missing link.
Björn is Björn, one of the best constants of my life.
