Complete the text messages between two friends planning a top-secret surprise party by dragging the correct phrases into the gaps.

"Don't worry, I won't tell anyone about the surprise party on Saturday. I promise I will keep my mouth perfectly zipped until the big day!"

"Don't worry, I won't tell anyone about the surprise party on Saturday."

We use "will" (or the negative "won't") to make promises and assure people about our future actions.

"I promise I will keep my mouth perfectly zipped until the big day!"

The word "promise" is a huge clue here! When we promise to do something, "will" is the standard verb to use.
