For real. Some people really get under your skin and being a muggle, you're unable to send them a letter which will shout in their faces in front of whoever is around them and then explode in a fit of rage as soon as your 'angry voice' has finished everything that you have to say. So your text is pretty much always written in capital letters and ends with *Your phone starts to explode* and *drops mic* at the end of every message, just so they understand how upset you are and are the universal trademarks of a Howler.
