However, it's better to say thank you late than never at all, so don't give up on sending a letter of appreciation later if you feel that this is appropriate.

然而表达感激之情比不表达总要好，所以不要放弃写感谢信，即使你觉得这个时候才写是不合适的。

Never say goodbye when you still want to try, never give up when you still feel you can take it, never say you don’t love that person anymore when you can’t let go.

当你仍想继续，永远不要说再见．当你仍然能够接受，永远不要说放弃。 当你舍不得他，永远不要说你不再爱他。
