Breathing Fire

Dave the cat was purring so loudly this afternoon that I remarked to Robbie that Dave was growling like a dragon. Robbie told me that dragons do not purr or growl because they are reptiles. I could feel my sanity draining away, how could we possibly be arguing about a fictitious creature? Well if the world had gone mad, I only had one option - to join in. I reminded Robbie that dragons breathed fire and that may not be easy for a cold blooded creature. I thought that would be the end of the conversation but Robbie plodded off to ask Sam if a dragon was a reptile. Sam listened indulgently for a minute or two, then he said "you have a choice, you can talk to me or you can talk to a psychiatrist!"
