I have a pet peeve. Well, actually, I have a few (remember, I'm still under construction), but one that has always stuck in my craw is when people don't say "thank you" in response to thoughtfulness, kindness, etc. Many years ago, a friend told me that whenever one does something from their heart, a thank you from the recipient should not be necessary. Deep down inside, I think that may be the right approach. But I'm not there yet. Clearly, there are some circumstances when a thank you isn't expected--for example, in the case of an anonymous gift to a known or unknown recipient. But when someone takes the time and/or makes an effort to show consideration to someone--and both the giver and recipient are known--I think a "thank you" should be given. Nothing extravagant is necessary, but at least an acknowledgement and expression of appreciation. For example, "thanks for opening or holding the door for me; thanks for letting me go before you in line at the grocery store; thanks for bringing me coffee; thanks for the thoughtful card and/or gift"; or waving to someone who allows you to move ahead of them in traffic, etc. Just common courtesy. Living abroad has made me more open-minded about many things, and I've learned a great deal about different cultures. But no matter where I've traveled or who I've met, a simple "thank you" in response to a gesture of kindness seems to be universal. Common courtesy. . . is it really too much to expect? Maybe. But I still have a ways to go on this one.
