Dear Heloise: In response to all the letters that you’ve printed in your column concerning “thank you” notes, I wanted to add an important element. Not only is a thank-you note a kind way to show appreciation for something that was done for you or given to you (whether you liked the gift or not), it also lets the giver know that you received it.

When I send a gift by mail, I always appreciate knowing that the person actually received it. Mail can go astray for many reasons (including theft), and it’s a relief to know that my gift arrived.

Given how easy it is to send a text or email, I’m surprised at the resistance in sending a note to thank someone for thinking of you. Wedding presents should always be acknowledged with a handwritten note to the giver, but even an email could suffice in this era.

I enjoy reading your column in the Dayton Daily News and the Xenia Daily Gazette. — Leslie Bates, in Xenia, Ohio

DOUBLE-DUTY COOLER

Dear Heloise: I am a faithful reader of your column in the Long Beach Press-Telegram. Coolers aren’t just for keeping beverages and other items cool. Just as a thermos can retain heat or cold, so can the coolers that we are used to filling with ice.

When I am taking barbecue or other foods that need to stay warm, I heat a brick (sometimes two) on the barbecue, wrap it in a towel, and place it in the cooler. Note: If using this method for meat, one might want to cook it below the desired temperature as it will “coast” to a higher temperature in the heated cooler. — D.C. Smith, via email
