Technology is our Friend...

I keep telling myself that every time my Blackberry (or crackberry as I like to call it) buzzes and email interupts another dinner out with Sean, or the phone rings and I have to hang up with my mother to take whomever is calling the work phone. It's supposed to make life easier, and it does. It also is an umbilical cord to the office/work 24 hours a day - 7 days a week, and I'm not sure how I feel about that. I love my job, but I work alot of weekends (and I'm okay with that) but at what point can I put the bberry down and not worry about it? Can someone please explain it to me? Like I'm a 5 year old?
