如何用英語(yǔ)委婉的表達(dá)“去衛(wèi)生間”

I never had in our family.

Would you mind I. to go to the toilet？

用英語(yǔ)委婉的表達(dá)“去衛(wèi)生間”的說(shuō)法有：
1、I need to go somewhere.

我要出去一下。
2、I want to wash my hands.
我想洗手（指想去上廁所）。
這句話隱含的意思也是“我要上廁所”。女生說(shuō)得更客氣的一句話是“I need to powder my nose.”，是很含蓄的說(shuō)法。 而“I want/need to go (or use) to the bathroom/restroom_ ”則是比較普通的委婉了，程度沒(méi)有上面兩個(gè)高。
3、I need to answer the call of nature.
我需要回答大自然的召喚。
一種更為文雅的說(shuō)法稱(chēng)內(nèi)急為“the call of nature”，那么上廁所就成了“to answer the call of nature.”。有時(shí)個(gè)別年紀(jì)大的女士在這種情況下還會(huì)說(shuō)“I need to make a pit stop.”
