You always ask for that. You always brag with how bright you are and how much you know but for trivial matters like this you seem to have no answer. Why is that? I tend to view you as a very petty person in all things you do with your life. It seems to me you hope for others to help you rather than think independently. is that your life in a nut shell? How sad to see a people who lack the simplest skills in comprehension. You talk so big all of the time you should be able to figure the answer to your question on your own. Go do your own homework.
