I'm sorry I won't be able to keep our appointment for this afternoon. Something unexpected came up.

很抱歉，今天下午我不能赴约了，我这儿冒出了点事儿。

Do something special for the special one in your life, remembering that in matters of love, it is better to be sorry for having risked and lost, rather than to have not risked at all…

为你生命中特别的那个人做一些特别的事吧，因为凡与爱有关的，因为风险或失去而有所缺憾，要远远好过一点风险都没有经受过…
