A teacher sent out an announcement that her class would have a day off tomorrow.

One of her students comes home to tell his grandfather.

I don’t have to go to school tomorrow, can you take me to the park?

He agrees.

He immediately calls his secretary at work.

Something came up so probably we can’t meet up at the hotel tomorrow, let’s do it some other time.

She agrees.

The secretary texts her husband.

Hey honey, I don’t have to go to that conference out of state anymore. Wanna stay in and do something tomorrow?

He agrees.

Her husband then gives the teacher a voicemail:

Man, my damn wife is staying home tomorrow. Don’t come over!

Disappointed, the teacher retracts her announcement and requires her students to come to class again tomorrow.
