I just recieved a histerical phone call from my mother. She just "broke up" with a guy who she was going to dinner with (although she told him she wasn't interested in him as a lover). Apparently, other older guys were coming up and talking to her... why my mom is still going to these places and attracting men baffles me. Anyway, apparently this guy took it the wrong way when she was talking to these other guys and totally flipped out. He drove her home, and left. They were scheduled to go out the next evening but they just didn't call eachother.

Fast foward to today. Apparently he comes over and leaves a letter containing a poem (said something along the lines of; you broke my heart) and a single black rose at the guard desk to my mothers condominium.

My mom thinks the guy is apeshit and she's going to get murdered.

Anyway, what is the meaning of the black rose? Apparently he's from Guatemala, if it has something to do with Guatemalen culture. I Googled it realy quick and couldn't really find anything. Some websites said that it signified death, other said "loss of love."

Should I be worried about this? Do I really have to make a phonecall to this guy to scare him shitless?
