She's always working late, she's a real busy bee.

The garden is buzzing with busy bees.

I'm sorry, but the line is busy right now.

Busy beavers build dams to create their own habitats.

The busy bodies in the neighborhood always gossip about everyone's business.

I'm busy

I kept getting busy signals when I tried to call my friend.

I am getting busy with work.

I have a busy box on my desk.

The children played with the busy boxes in the classroom.
