A man called me and said, "hello?" I replied "hello?" and he hung up. I called the number back, asked whom I was speaking to, this time it was a woman who identified herself as "Laura Black". She wanted to know who I was, I asked what it was in regards to and when she wouldn't tell me I hung up. Then a differet number appeared (I erased it accidentally) left no message, and paged me via my cell phone asking me to call them back. This is random and unsettling.
