Hums

Mary often hums a tune as she works in the kitchen.

My head hums.

He always hums while working.

Do you know anyone who hums while they work?

Tom always hums while working.

Mary often hums songs under her breath while she works in the kitchen.

It hums in my ears from the yell of young children.

Tom always hums that tune when he's washing dishes.

The air conditioner hums quietly.

The sea hums with wisdom.
