Texting is a tough one because I have some friends I've known for 30 years that text once in a blue moon, but really never enter into a conversation. It might just be an errand thought or dumping a news item. There are others who immediately delve into a long drawn out conversation because that's what texting is to them. If I really need to speak to my friend of some 30 years, I will call him and then we could talk for hours, but texting? Lucky if I get two responses. So if I were in your shoes, I would start defining who are conversationalists in text and others who need a phone call. People are not all alike, so their forms of communication will differ as well,
