Dialog 1 back on one's feet [ 立ち直る、回復する ]

Angela:Who's the greatest athlete of all time?
Yukio:I think Lance Armstrong is pretty amazing!
Angela:Why, because he's won the Tour de France seven times?
Yukio:Well, that too. But mainly because he had cancer and was back on his feet winning another Tour de France within a year!

Dialog 2 fall on deaf ears [ 無視される ]

Yukio:Guess what. My roommate Skippy left without paying rent and he stole my girlfriend again!
Angela:I told you it was a bad idea to let him move back in with you!
Yukio:Well, I guess you did tell me that I was a knucklehead for doing that.
Angela:Yeah, and it fell on deaf ears!
