What are you supposed to worry about when you write? Spelling, grammar, and punctuation. And everyone learns these tools in school (in theory).

So let's discuss this little mark.
No writer is perfect (hate to break it to you). Everyone has off days, mental synapse fails, and finger slips on the keyboard. Avoiding sharing such embarassments with the world is simple with the invention of such AI programs as Grammarly. However, there's a catch: the programs AREN'T infallible.
