I have actually lost what had been a friend for most of 50 years because I do not carry my cell much at all unless my wife is gone somewhere.( we both work at the same place for 27 years so I don't carry it much.) He thought I was not answering because I didn't want to talk. He could call me at home on the home phone but I guess that was not when he wanted to talk. Really hate this but I still do not like carrying cell phones so I don't.
