I attempt to write in a that some one can understand other than me, but my writing always end up sounding like like a gurgled mess. As I continue to write my writing becomes clearer and clearer, at least I hope, and my ideas are understood more easily. this relates to a cloudy day in the way that the cloudy block out the sun. When clounds block out the sun the sun's light is blurred or even not visible from the ground, but as time goes on (or in my case the more I write) the sun reappears little by little until it is fully visable (again in my case when the idea i am trying to put across is clear to the reader). By the end the day, week, or month, the clouds have cleared and the sun is able to be seen but one can always remember the cloudy day it was right before that moment.
