Complete this friendly cafe encounter by dragging the correct words into the blanks.

Alex: "I'm so sorry for keeping you waiting!"
Sam: "No worries, I was just enjoying my coffee."
Alex: "Thanks for being so understanding. My dog decided to chase a squirrel!"
Sam: "Don't mention it! We've all been there."

Alex: "I'm so sorry for keeping you waiting!"

We use for + gerund (-ing) to apologize for an action. ("Sorry to keep you waiting" is also correct, but "to keeping" is grammatically incorrect.)

Sam: "No worries, I was just enjoying my coffee."

"No worries" is a very common, natural spoken expression used to respond to an apology.

Alex: "Thanks for being so understanding. My dog decided to chase a squirrel!"

After "being", we need the adjective form understanding, which describes someone who is sympathetic and forgiving.

Sam: "Don't mention it! We've all been there."

"Don't mention it" is a fixed expression used as a polite and friendly response to someone thanking you.
