​@ajcook: 16 years ago today I married this fella. Let's be honest. We were babies!! Yet, somehow, here we stand. Solid. Steady. Secure. I am overwhelmed by the good, we're stronger because of the bad and we have our two crazy boys to thank for when it all gets ugly. Love you @nathanandy #marriage #snugglebuddy
