I just got a call from a telemarketer. She offers real estate advice and even offer to visit me at home.

Really? My number is a (703) prefix, back from when I used to live in the east coast. I live in California now. So I ask her again if they'll come to California. Of course this is waaay out of their script so she shuffles and hesitates while trying to find the appropriate response. Eventually she says "so... you live in California?" --well, yeah, that's what I said 5 minutes ago; "well, we can send you some information there. What's your address in California?", she asks.

Smart! telemarketers are outsmarting me! Should I give her my address? uh, no.
So I say: "HA! so you can send me crap over the mail on top of calling me?". She replies "well, we can email the information to you, if you want". Crap! what should I do? give her my email address? uhhhh, no? "how about you send me your don't-call-me-again information, along with the add-me-to-your-do-not-call-list brochure?".

Geez. I can't believe this is a profitable business.
