When something happens out of the blue, it happens suddenly without any warning. It’s a surprise. It could be positive or negative.

In American slang, When there is something that we do not like, or we find unacceptable, it’s popular to say that something is not your cup of tea. If you like something or you are good at it, feel free to say, ‘That’s My Cup of Tea’ or ‘It’s My Cup of Tea’. They both work. You can be specific: Speaking English is my Cup of Tea. We use the phrase with actions. Here’s a short, fun video for more information.
Remember, this phrase is used for physical actions or things that you can do. While I wouldn’t say that ‘learning English is my cup of tea’ I would say that teaching English is my cup of tea. What are you good at? What’s your ‘cup of tea’?
I often like to ask my students questions beginning with the words, “have you ever”. The question asks if the person has ever experienced a certain thing. For example, I might ask, “Have you ever been abroad?” I want to know if my student has traveled outside of his or her country at any time in this person’s lifetime. I have found that a lot of people are confused when they answer those “have you ever” questions. This video explains how to answer them.
