Typos are one thing I always pretend I haven't noticed with other people - I think to some extent that stems from the five years I worked for Umbridge (for context, it was a big thing of hers that she'd tell people off for typos, on at least one occasion sending someone a shitty email about a typo that wasn't actually a typo at all but Umbridge mixing up two people with similar surnames, and yet she made more typos than anyone). I can't bring myself to "be her" and notice.

Since I type mine into Word first before posting anywhere else that does catch some, but there might be things like people's names or something that exists as a word that it doesn't notice. I think the ones I do have to go back and change are where it's veered into the wrong tense.
