But as I am apparently your best friend, I cannot congratulate you on your choice of companion. Actually, now I can.

尽管我是你的好朋友，我还是不能祝贺你的婚姻。事实上，现在我要祝贺你。

Still, in the main, choice of companions can be made, and must be made.

不过，总的来说，可以而且必须选择同伴。

Purity begets purity, like begets like; and this fact makes the choice of companion in early life more important even than that of teachers and guardians.

纯洁生纯洁，物以类聚；这一事实使得早年伴侣的选择甚至比老师和监护人的选择更为重要。
