Weird acontecement

I will tell us something that happened to me and it was strange

It was a school day on Wednesday and the principal said: Hello students, be late Enter on Thursday and Friday. But I didn't hear that it was late enter on Thursday and only friday .

So the next day, Thursday, I am getting ready for the school day, I got to school and a school administrator opened the door and she said hello there is late entry for this day and tomorrow.

so i had to go back to my house
