Feel Feel? that won't do any good I would have done that in the first place. If I felt I could. Could you repeat what you were saying? I still can't hear. Please speak up and make it clear. Any deaf person would have heard the caller shout, With my mouth wide open, I tried to work it out, I screamed back; what did you say I've done? Madam, you have won the lottery, a tidy sum. I was speechless, struck dumb.
