Currently, I'm reading Rain Reign by Ann M. Martin and a quote that I like is "If I ever think of another four-homonym group, it will be a red-letter day."
I find this quote interesting because I don't know what 'red-letter day' is. I have some questions about this and I hope they will be answered soon. I have a few ideas but there nothing really to go for of. This is why it's interesting, I want to know what it means and what will happen. Hopefully I find out what red-letter day is.
