It's just that I don't have my phone with me at all times. I'll forget it at home, in the car, etc. And sometimes, I'll leave without my phone on purpose. It's an amazing feeling and really liberating knowing people can't get in contact with you.I can understand if your at work, class, driving, or with friends. But if your not picking up your phone cuz you " don't feel like it". Well then your just being mean.
Obviously not working with other people and people not depending on me helps. When I'm waiting for a call or a message, sure I'm a little more vigilant and will turn on the ringer.
