Text: this happened about a hour ago;

so this morning was my first day back to school. 

just after finishing my breakfast i was quite in a rush. i still had to print my documents​, take my shoes and rush to my bike because it was going to rain. (rain is a big deal when biking)

so here's where my tifu goes on. i had to send my documents to my printer and at the same time i was heading to the closet to get my shoes. my mom entered the room and "closed" the door. as i was looking down my phone i did not hear it and went straight to it. at the precise moment i was in front of the door (that i thought opened) i sneezed strongly and hit the door. my head crashed right into one of the the tiny windows and my mom screamed at me "what the heck". i went straight into it and didn't understand what just happened.


now i'm sitting in class with adhesive bandages and scratches all over my face. everyone stared at me weirdly when i entered the class and i'll have to explain why i've got all these marks on my face the whole week.


please don't mind my english but do not hesitate to correct it ^^

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
