Things you should never let come out of your mouth without first thinking twice:
It's no trouble at all.
love dogs.
We have plenty of room.
Call me any time.
Is there anything I can do?
My husband is a doctor/lawyer/accountant.
I'll try anything once.
Of course, bring the kids.
Why don't you stay for dinner?
If worst comes to worst, you can use mine.
Don't worry there's more where that came from....
