And I think it is fair to say that it is ridiculously dramatic. Which is okay, of course, I'm not criticising here. Just like it would feel ridiculously dramatic (at least to me) if someone explained that they cried today when they stopped their subscription to Netflix in order to move to another service, because they love Netflix so much.
