Me (14y male from Poland) got my english teacher annoyed/disappointed after saying the word “crap”. I’m unsure if this is the right place to ask this question but is saying that word considered bad? I always thought it was pretty mild and not a big deal.
Knowing that English is a second language for you, she’s probably trying to help you!
Maybe assume that your English teacher knows a bit more about the language and how and when to use it than you.
