Sing for me?

I wait outside grandpa's door patting patterns with my feet when he calls me in. He comes to lift me, thinking I woke up to the rumbling thunder. I shake my head.
"No? Then your nosey?"
I nod. Colds are nightmares.

"Okay, sleep on my shoulder?"
"Will you sing? LaLaLal'ah"
It's the sacred notes hummed to make me sleep. A ritual on every cold/cough.
He sings.
"Grandpa? Walk?"
"Okay, Lala,Lala. Lala,Lala"
After a few minutes, he sighs into a chair, yawning.

"Grandpa...?"
The ritual begins again.
"Grandpa, it's LalaLal'ah not LalaLala"

I lulled. He still hummed in his sleep LalaLal'ah...
