请你们帮助我翻译这汉语文章. (Please anyone help me translate this Chinese sentense.)
I need to translate this conversation, originally came from 'Morihua Kai', for homework
(back ground information : They are arguing about whether to keep chamberpot inside of the house or not. And Lili previously suggested Joujie to keep the chamberpot outside, but he disagreed.)
Lili : 我一闻到这气味就头晕晚上睡不好
*It's what she responded to the smell of a chamberpot.
Joujie : 好了,你就是改不了资产阶级生活习气
*Lili came from wealthy family, but Joujies' is not. And he's very proud of where he came from.
Lili : 我什么都能改..这..我坐上面上不出的
I do understand most of those sentenses,
but It's that last sentense '我坐上面上不出的' which perplexes me.
Please help me translate this one. It's kind of urgent.
请你们帮助我翻译这汉语文章, '我坐上面上不出的' .
