附Ted在第二季末尾说的: So Marshall and Lily were married and I and Robin were broken up. And it's hard for us that time, but in the end we both got what we wanted... I think for the most of the part if you really honestly treat yourself about what you want of life, life gives it to you.
Couples like Marshall and Lily should get married. But couples like Robin and Ted might just love each other and say bye.
事实上Marshall and Lily也只是个乌托邦,我不信这样的情侣真的存在. So maybe most of people just love and say bye.
