WhatsApp has become my default way of communicating with a few occasional emails or phone calls.
I do have one friend who is becoming a bit left out however. She does not use the internet or a smartphone, dislikes phone calls except for business/commercial purposes and loves receiving and sending hand-written letters. We live a couple of hundred miles apart so can't meet very often. I've explained that I find it difficult to make time for hand-written screeds but she just says, "well, try!"
Sadly, although she's been a good friend and emotional support in the past, she's in danger of becoming a lost contact.
