Why wouldn't I? We talk on the phone, sometimes have video calls (usually in groups) and occasionally use SMS as a fallback if a call is not an option. E-Mail is also sometimes involved if it's a more in-depth exchange or something involving E-Mail anyway (booking confirmations and the like).

edit after re-reading: I didn't mean to make my original comment sound like there is only real life. Just that not liking and not engaging with more or less continuous modes of communication and notifications does not equal not interacting with people.
