I find most phone chats annoying and time wasting. Invariably somebody will ring at a most inconvenient time - such as when I'm trying to cook dinner. So I much prefer texts, which, like in the old days of letters, wait for your convenience for a reply. If I want to talk to people I arrange to see them for coffee or lunch. My family visits once a week or so. One of my sons is in Vietnam at the moment - we use Facebook video call once a fortnight. I like getting texts - they make me feel involved in people's lives and are not intrusive. The phone ring tone seems like one big nag to me! I've not installed Whatsapp because I already have my phone company repeatedly telling me I'm short of storage space and the apps I already have can't be updated unless I create some space! This, of course, is very irritating, since I don't want to delete photographs etc.
