Caller ID

I gave my phone phone, with caller ID, to my brother, and now I'm using an old-timey phone without caller ID and without an answering machine. And I just can't stand it. Even though all my friends know to call my cell phone, I still can't stand to not answer the home phone when it rings. And it's a telemarketer EVERY TIME. But I still can't just let it ring and not find out who it is. So now I have to go to Target to buy a phone with caller ID.
