Irwin: Rolling out the welcome mat

It seems to me that I have heard the phrase “you’re welcome” less and less over the last few years. It has been largely replaced by “thank you,” ironically enough. When one says “thank you,” the response is often “thank you.” Such an abundance of gratitude is wonderful, but it can also seem a bit insincere at times. When I listen to HPR in the morning, I hear a journalist thank a guest, and the guest (or correspondent or other journalist) will reply, “Thank you for having me.” Same with late night talk shows and other such venues.
