On the flip side, I read a study that said that texting is a way to avoid marital fights. The study reported that couples will text each other regarding where and when to pick up the kids, thus avoiding any potential dispute about a possible negative tone in the way the correspondence transpired. (This is so because there is nothing vocal in a text. One can also insert a smiley face on the text, which will often bring cheer to the text’s recipient.)
So please stop being so hard on yourself. As you try to improve your technological skills through study and course taking, maybe you can teach your younger colleagues a thing or two about how to build relationships – a seeming strength of yours. Hatzlachah!
