I have no idea how to spell the day after tuesday.
Why do you not know how to spell it?
It's just difficult and looks weird.
Wednesday is a hard word. You should learn how to spell it, though. It's fine to make mistakes.
Nah, I have tried to remember. I can't. I usually just use the calendar on my phone to check the days.
It's great that you admit that you don't know how to spell all of the days of the week and that you have figured out a way to make sure you have spelled the words correctly.
