 You think you hear phantom rings and you check it and jump up in the middle of the night. Maybe it's just a Facebook notification, Instagram or whatever app you have. All those needless and meaningless communications that occur in the middle of the night. Your phone being your bedtime friend, or should I argue your bedroom friend, leads to sleeplessness, loneliness, isolation. It's a killer for hobbies, for romance, for conversation if you're married.
