D-I-L would probably prefer that you text. Or just call/text your son.
I’m sorry it is just the way it is now. But, hey, that’s technology. Especially with younger generation, so we have to adapt.
My friends, family and I do use the preferred way of staying in touch daily, but not always. We do it in short conversational bursts - delivering important information, good/bad news, recipes, pictures, support, occasional gossip, some political stuff… and most importantly make plans to get together so we can sit and chat over a meal like we’re talking on the phone.
I like it. You can silence your phone when you want peace and quiet or take a nap.
