Teacher: In this task, you are given a Reddit post as a text. Your task is to generate a short summary for this text. The summary must include a situation which caused humor. The summary should be one or two sentences long.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Text: quick backstory: i am a duel enrollment student (still in high school but goes to college full-time) and don't have my license so i bike home. 

now let's get to the fuck up. i was riding down the sidewalk and up ahead was a golf cart blocking the way. the man who was using kindly moved it out of my so i could get past. as i go by, i give him the nod and say "thank you" just to be courteous.  well he didn't really give me that much space so as i was saying thank you, my goes into the grass and i quickly try to readjust, resulting in my tire hitting the side of the sidewalk and me falling off my bike. i looked like a complete dumbass and just laughed to myself and kept riding.  luckily, i don't take myself too seriously, so i wasn't that embarrassed.
Solution: said thank you, fell off my bike.
Reason: This summary is appropriate for the given text post because the focus of this post is about a humorous situation caused by "thanking someone and later falling off from the bike".

Now, solve this instance: Text: so i was at the office working late,  must have been something like 8 o'clock, and because i had a lot of coffee during the day i was taken by an urge to go the bathroom. 

i rush to the men's room, sit, pull out my phone and start playing candy crush. 

one minute later the door burst open in a thunderous noise, and i am left face to face with the boss of my department, pants pulled down, phone in hand. we stare at each other during what seemed an eternity, after what he finally closes the door and walks away without saying a word.
Student:
forgot to lock the door of the bathroom, boss entered.
