People who keep nagging me to get a bloody cellphone.
My sister gave me a basic Samsung one a couple of years ago. It's been sitting in a drawer for most of those couple of years. I got a younger friend of mine to make it go again, and it's handy to take photos with as I don't have a digital camera any more.
Can I make phone calls with it? No, and I don't usually carry it around anyway.
Can anyone call me on it? No, I don't know its phone number anyway.
