<U>My response</U> :  &nbsp;&nbsp;What you write in your response/comment is very unnatural to be true. &nbsp;&nbsp;&nbsp;&nbsp;I do not believe in it.



Hello, is my understanding correct that you are not able to re-write properly from the text ?


Or you obtained your problem via the phone ?



Also, check your keyboard, if it works properly.



Also, check your glasses (if you wear them).


May be, there is a spot on a glass which obscures your vision.
