It is easy to forget. But this is great advice to students.
Sometimes students want to come up with the most complicated sentence in the world when all they really need is something simple and easy.
After all, most of our daily conversations are simple. They start off that way at least.
What did you do last weekend?
Was it fun?
What did you eat?
Rarely, if ever, do we ask something like, “If it were the first time you ever visited this place and you had a lot of time, and you could speak with dolphins, what would you ask the Dolphin King?”
It’s nonsense and it’s just too long.
For students just starting to learn the fundamentals of communication, it is easy to forget. But simple is good.
