Whenever I hear the phone ring on TV, I just figure it's for one of my 4 daughters. I never bother to answer the phone, because I know the caller is stephanie, katie, Caitlyn, Kayla, Lucy, etc...
Sometimes I wish I weren't on the Do Not Call list just so *I* would get a call for me.
Not to worry. Your daughter will have her own cell phone soon enough.
(Actually, I don't think that's such a bad idea. I hate cell phones, but there are no more pay phones. One call to 911 will justify it.)
