The opening weekend for Avengers: Endgame is impressive, but that doesn't mean everyone has gotten to see the film in its first few days. One teacher unable to see the movie until next week has taken a fun approach to warning his students not to ruin the movie for him.

A student posted a photo on Twitter of a note her teacher had posted on his door, pleading with students not to spoil Endgame for him. According to the note, which you can read below, the teacher is waiting on his brother to return from a business trip in Tampa in order to see the film. Unfortunately, that means he has to wait until at least Wednesday. In order to ensure he isn't spoiled by students, he asked that students do not discuss the film anywhere near his classroom until he has taken down the note.

The post sparked some negative comments about the teacher, but the student defended him, saying, "Please stop saying its [sic] bullying or whatsoever. Its [sic] all humor guys!"

Although the note may seem extreme, it's nowhere near as bad as an incident that reportedly happened outside a theater in Hong Kong. A man was allegedly attacked outside of the theater after loudly revealing spoilers at the theater's entrance, resulting in a group of fans attacking him.
