"Buh!" says my boy as he pops his head over the board in the kitchen doorway, "Buh!" as he pulls his blanket sideways across his eyes and then drops it suddenly to the floor, "Buh!" as he spots me coming round the corner smiling his own special smile, "Buh!" as he spies me lurking stealthily with a camera, "Buh!" as he jumps up beside my knees and lays his head on my lap.
"Boo!" I respond roundly each and every time, wondering how a sound that vaguely resembles a noise, that's not really even a word, can bring me flashes of such unbridled joy so many times a day.
