My favorite Andrew memory is when we were little, and we had the white metal bunk beds. He would ask me to tie him up to the bed, and he'd try and get out. I would think and think and try to come up with the most impossible knots and weave the rope through the slats underneath the bed. But, somehow, 5 minutes later, he'd come and get me and ask me to do it again.
Happy birthday, Andrew.
