He is a sensitive boy.
He loves music, he feels music.
There are some songs he finds have a sad tune, like Twinkle Twinkle Little Star. When that song plays, and if it catches him in the right mood, he tears up.
He LOVES the music on our local news station (the intro/exit music).
He gets so excited when he hears it.
Then at the end of the broadcast local children wave goodbye.
Then suddenly all the music, and all that waving is gone, and it makes Alex tear up.
Sweet, sensitive, sad, silly boy.....
