She asked me to find an old song. I'm adept at that, so I found it and played it for her on the telephone, as well as sending the lyrics to her son's computer. (he lives there to watch over her) A couple of days later, he called me. He asked me not to do that again, that she'd bawled steadily from my call for two days, and was still sobbing.
It hurt me to know I'd helped to make it worse.
