Hummy Sunday

Sunday a.m., pretty early.
I have my first cup of coffee
...and a Sudoku.
The little guy is behind me, puttering with his Legos.
The sun is shining on me through the window.
It's making me warm.
Throughout, he's accompanying his fantasies by humming.
Just a little hum, kind of random and wandering.
It's hard to pick out one tune.
The hum just loops around in his head and mine.
