I have some friends that I haven't spoke on the phone for years. We usually message we each other. I've ask my kid why she never make a phone call. Apparently no one actually talks to people on the phone unless it's non friend related thing. I wouldnt worry about it, this is the era of communicating by typing messages or emails. Times have changed and at this rate people communication skill will go to crap. I dont understand most of the typing lingo.

Also everyone's so much busier these days. Making messening each other a lot easier.
