Today we answer a question from Melsom in Iran."How many ways can we say ‘you're welcome?'...How can we reply to them in both formal and informal ways?"Dear Melsom,We thank you for your question!Let's take a look at the formal answers first.These would be ones that you may use with people you do not know very well.They include: "you're very welcome" and "my pleasure."Here is how two co-workers may use them when speaking with each other:Thank you for helping me finish the project.Of course. My pleasure.You may hear, "my pleasure" at a popular American fast food restaurant.The company might tell workers to answer with ‘my pleasure,' when people say "thank you" to them.This is both a formal and kind way to speak.Now, let's look at less formal ways to say "you're welcome."They include: don't mention it, it was nothing, sure thing, anytime, and no problem.For example, suppose your friend helped you fix a problem with your computer.Here is what the two of you might say:Thanks for all your help!No worries! It's not a problem for me.After saying, "You're welcome," you can choose to add some of the other expressions, too.Like this: Thanks very much for the ride downtown this morning.You're Welcome! Don't mention it. It was nothing. It is easy for me to take you; I'm happy to help.And that is Ask a Teacher!
