Dialog 1 on the wrong foot [ 悪いスタート ]

Angela:I never thought that you two would be a couple!
Yukio:Really? Why is that?
Angela:You two started off on the wrong foot, remember? You commented on how big her head was when you first met.
Yukio:Oh yeah! That was funny! She got really angry! I bought her some chocolates and apologized to her. Things have gone smoothly ever since.

Dialog 2 You have to fail to succeed [ 失敗は成功のもと ]

Angela:I can't stand up! Surfing is so hard!!
Yukio:Don't worry about it and keep trying.
Angela:But I keep falling off my board. Sometimes I'm too far forward, get up too late, or my feet are in the wrong place.
Yukio: See, it looks like you're learning. You have to fail to succeed. Keep trying, you'll get it!
