---------- Forwarded message ---------- From: remanuel@xxxxxxxxxxxxx Subject: Re: unless conditional It's all about double negatives making positives. Perhaps this clarifies it: If the seas are clean, the fish will live.= Unless the seas are not clean, the fish will live. If the seas are not cleaned up, the fish will die.= Unless the seas are cleaned up, the fish will die. If the seas are polluted, the fish will die. = Unless the seas are not polluted, the fish will die. If the seas are not polluted, the fish will survive.= Unless the seas are polluted, the fish will survive. Happy Chanuka to one and all!
