| You took the words right out of my mouth. | Somehow you knew what I was going to say. |
| I was born with a silver spoon in my mouth. | I was born into a rich family. |
| It made my mouth water. | I felt hungry. |
| I had my heart in my mouth. | I felt anxious. |
| Why are you so down in the mouth today? | You're very miserable, aren't you? |
| You look as if butter wouldn't melt in your mouth. | You're not as harmless as you seem to be, are you? |
| What you're asking for is pennies from Heaven. | What you're asking for is a miracle. |
| I'm determined to succeed come hell or high water. | Whatever happens, I won't give up. |
| It's time you waved the white flag. | I think you'd better admit defeat. |
| I want your promise in black and white. | Please put it in writing. |
| It was only a white lie, so I hope you'll forgive me. | I didn't tell you the truth, but for a good reason. |
| Living with you is Heaven on Earth. | Living with you is everything I've always wanted. |
