person A: Im going to ask my girlfriend to marry me this weekend! I have no doubt in my mind she will say no
person B: That is so exciting! Best of luck to you man! I doubt she would reject such a great guy like you. :) 
person A: Thanks! I think we are doing well so i wont be disappointed or sidetracked by a no from her.
person B: That is great_comma_ I would also be surprised if she said no to a man like you!
