end it with a dash

I sit on a wealth of knowledge - the Norstedts Swedish-English Dictionary - and have a glass of red wine. A handcrafted candle - Christmas present from my niece - is spreading (probably) toxic paint fumes in the room. I have Christmas flowers - hyacinths and hippeastrums. I have contributed to Wikipedia today - only with knowledge. I wish I had the answer to a mystery and was the only one on earth to know - I would write it in my diary just in case I was hit by a snow plough on my way home from work. I would end the entry with a dash like this - so that people would think I had something else to say but it is now lost forever -
