平時就說"I need to go to the bathroom."
美國人說話很含蓄,就說上廁所,不具體報告“我要上大號”和“我要上小號”
小朋友壹般情況下也和大人說得壹樣,碰到有緊急狀態,就會說"I need to go to the bathroom. This is an emergency."偶爾聽個別人說"I need to pee."如果有人說,"I need to go to the bathroom. My stomach hurts."那妳就明白他是要"上大號"還是"上小號"了.
另壹個表現美國人含蓄的地方或可說是很顧及人的感受的說法有,如果有小朋友尿褲子,也只是說 Dave has an accident."
