In fact, try it with something more emphatic, like “You’re quite welcome,” or “You’re very welcome.”

This especially applies when the person thanking you probably did not anticipate there was ever the possibility of a problem to begin with. For instance, one pays a cashier and receives change in return. The payer says thank you. When you, say as the cashier, respond with the no problem retort, I always wonder where the problem was ever introduced that now I am being reassured it actually is not a problem.

The answer to “thank you” is still “you’re welcome” and despite foreign language inconsistencies (German: keine Sorge means no worries; Spanish: No problema means no problem) in English the answer has been and always will be “you’re welcome.”

There might be times when the no problem idea works like when there actually seems to be difficulty and you wish to assure the speaker you have no problem acquiescing.

And take special note, that when you write this out, as in an email, it is the contracted form of “You Are Welcome” so it is written “You’re Welcome” and never, never “Your Welcome.”

Smile when you say it and try to find in your heart the meaning and the appreciation going both ways.
