Earlier today I got a call to my cell from an unknown number. I missed the first 4 calls but answered the last two. It was a male, I believe, who only grunted an undistinguisable word or two after a very long silence. I blocked all unknown calls. Just a few minutes ago my phone rang twice and I answered and there was silence. It was 712-432-7931 that had called. If this person is just making up numbers to call across the US, then it must not be someone who know me. What a weirdo!
