I don't want to go back to a world without the internet or cell phones, but I would like expectations to change. Just because you can theoretically reach me at any time doesn't mean I'm obligated to respond to you or acknowledge you at any time. Whether it's work or personal acquaintances, I can't stand it when it's treated like a horribly rude thing to not immediately acknowledge and respond to any communication, no matter how trivial. A lot of times, I'm busy working on my own thing and don't want to kick off twenty minutes of back and forth texting over some trivial thing that's going to distract me from what I'm doing.
