Related issue, my sister and mom do not use the Internet at all. They're quite proud of their technophobia. It irritates me to no end. They're supposed to be on my emergency contact list, but I can't put them there because they're not reachable. They always have about 8 excuses every time I bring up the problem. Somehow, it always becomes my fault why I can never reach them in a timely manner.

Also, having an uncharged cell phone is usually a planning error. My sister's cell phone is always off and seldom charged. Don't be like her. If you don't have a charger in your car, you should buy an extra one specifically for your car. I have five chargers: bedroom, office, both cars, and laptop bag. I bought my charges in bulk from EBay, super inexpensive and actually better than the original.

You need to be at least somewhat connected. I consider my connectivity to be a responsibility to my loved ones. It's so easy to be connected nowadays. Things like Facebook and Twitter are point-and-click FREE services. The computer geniuses have made it so easy for for all of us. In this day and age, there is NO VALID EXCUSE.
