I do have a cellphone (my father pays the bill), which I use either for sending text messages to my friends (and receiving text messages from my friends) and for whenever I'm out of the house, without my parents.
I always have it turned on, except when I'm sleeping or at school. When I'm home, it's almost always near me, but it happens to have completely forgotten about it.
I never use it for long phone calls. It makes no sense; the standard phone is so much cheaper!
See ya,
