If my cell phone philosophy ever becomes "Life Is Too Short To Take A Potty Break," I'm going to have to re-evaluate my whole life..
Now those are words to live by!
To Chivewarrior, :
If it makes you feel any better, my Mom still feels that she can pitch a fit if I don't pick up, return, or place a phone call as often as she'd like. I'm extremely independent, busy, and 28 so I'm not clear why she thinks that she can dictate how often I speak with her but there you have it. Like others have said, you'll have to start setting those boundaries slowly yet persistently. Unfortunately there's not a lot you can do right now as (and forgive me for assuming here) your parents are probably still subsidizing your life.
