Kinda creepy

We had some chain-link fencing in our yard that we were going to put up but didnt get to it, and my neighbour had a deck she wanted to get rid of so I put them up for offer on freecycle. Well, I got inundated with requests for both items. I posted that they were taken and emailed every individual advising same. While I was out to the store, someone called and asked if it was still avail. Grant told me this when I got back. I got to thinking, hmm...where did they get my phone number. I didn't post it in the message. The person who called went to the trouble of looking at our email addy, than going to the phone book and finding it. I can't believe to what extreme this person went too. It is creepy and pathetic.
