IS IT BORING OR ANNOYING?
Spanish people get these confused all the time. For example: "I can never remember the irregular verbs, it is very boring!". This is not correct, in this context it is much better to use "annoying". We use "boring" when something is not interesting.
For example: "This film is really boring I am going to leave". "Annoying" is used more in the context of when something is irritating you. For example: "When everyone speaks at the same time it is very annoying".
Hope that helps!
