祝我一个人白头偕老
[zhù wŏ yī gè rén bái tóu xié lăo]
'Wish me growing old alone.' This is usually a wish expressed during weddings hoping a couple to be together until their hair turns white. Here it uses sarcasm, suggesting that even when wishing good luck, there's an acceptance that loneliness might always exist in the rest of life.
