No, we definitely need the internet. My father also works from home a lot. XP
Y'see, his paycheck pays for the house, and my mother's paycheck pays for the utlities, and what's left of that pays for food, and other supplies, which is becoming more and more scarce as time passes.
There's the money from my job, but that's for gas for my car, and is also being saved up for a low-end MacBook for when I return to college in August. It's rare for me to use it for food for myself.
My siblings like to use their money for food, though.
