That pesky fly that you give multiple tries to before you make your move.
And squash it.
Remind of that pest who keeps bothering you?

On social sites you block them.
Give them opportunities to find another to bother.
Except that pest doesn't get the message.

Kids, remind of you of this when they constantly won't stay from your space.
Then again,  adults can be a pest too.

Who hadn't heard?
That neighbor is a pest.
