So, I'm not familiar with this forum, but somehow I got obsessed with this riddle after a riddle-fanatic acquaintance asked me to send her a good one. I shared it with her, as well as my mother, stepfather, and another older couple, but no one has figured it out. I see that it was originally posted in November, so it has gone unsolved for over 3 months. Is that typical on this site? Is there a customary amount of time before the poster provides the answer (or an additional clue) or could this riddle remain active/unsolved indefinitely? I'm at an impasse.
