Doug and all, I do hope the meaning is not totally lost!   As the "time flies" example you gave used a clock, which is not acutally time but how we see it...the same is in this image.  Those candles, what kind of candles are those?  What would a little kid call those candles? 

I also hope I am not hopelessly out of the real meaning of the challenge...I think not.   Tom.
