我姐姐有洁癖。有一次，爸爸在卧室里不小心打了个大喷嚏，姐姐就逃离了卧室。
My sister has a habit of cleanliness. Once, my father accidentally sneezed in the bedroom, and my sister fled.
我还发现，她从来都不穿凉鞋，因为她怕灰尘弄到她脚上。她也从不光脚踩在家里的地板上。
I also found that she never wore sandals because she was afraid of dust on her feet. She never steps on the floor of her house barefoot.
还有一次，吃饭的时候，我的手不小心碰到了一片菜叶，姐姐大发雷霆说：“干嘛呀，这盘菜我不吃了!”开始我觉得姐姐说的只是气话，后来姐姐真的不吃那盘菜了。
Another time, when I was eating, my hand accidentally touched a piece of vegetable leaf. My sister was furious and said, "why, I won't eat this dish!" at first, I thought what my sister said was just angry words. Later, my sister really didn't eat that dish.
有洁癖的姐姐真是让我无可奈何。
I have no choice but to have a clean sister.
