Wherever we are, whatever we are doing - every time an airplane flies over (commercial, private, or military), he stops what he is doing, waves at the sky and shouts, "Hi Daddy!"
I wonder if he ever wonders why Daddy doesn't just land and come home if he's always constantly overhead. But of course, when my answer for his "I want Daddy" pleas is always "Daddy is in an airplane," of course he thinks that. If Daddy is in an airplane, then every airplane is where Daddy is. No matter how long Andrew is gone, this boy always says hi to him in the sky.
