I am going to do a little word association.
Diary, dairy
Now, diary is something you write. You keep it at home, in a private spot, because you don’t want the kids to read about your awkward childhood boners. Now, when you write the diary, you tend to eat dairy (admit the fact that you never saw that coming). Some of you disgusting people, I assume, like to write while drinking tea, or eating cheese. Some of you take it a step further and write things on top of cakes. You should be eliminated.
By now, it should be clear that I have no clue what I am talking about nor do I know anything about the English language. With that, I wish you a safe pandy, and a bright future.
