This is another great example of why auto-correct is the devil. This poor mother was just trying to tell her daughter she didn’t need any help, and instead she ended up doing the opposite – this is quite an alarming text to receive from anyone, let alone your parents.
Ideally, auto-correct corrects your typing according to words you typically use, but then what does it mean in this case? ‘Unhemmed’ is probably not a word that is regularly used by anyone, but ‘urinated’ is? I can see why her daughter was worried.
