The question in the title is not about the Christmas song, although I do love the music. It’s about my hearing aids. The first one was fine, but when I put the second in my ear, I couldn’t hear anything. No! Not today! I was going to get an injection in the eye and wanted everything else to work as usual. Don’t panic! That won’t help anything. I put the aid back in the charger, which should have cut it off and started recharging. The second time I could hear the tune it plays, but just barely. Could it be that wax had shifted, muffling everything? I didn’t think so. I put the aid in again, picked up the phone, and looked for the app that can control it. It wasn’t there! Could I have uninstalled it by accident? I began reading the titles of all the apps and finally found it under C when I thought it was under O. Changing the volume of both seemed to solve the problem. Whew! What a relief! The rest of the day was much smoother.
