Where do you live? Disagree your words...

Where do you live? My siter is not 过敏 in Shanghai, she got here in April after 10 days stay in Boston surburn area, she got 过敏...

As I said in early post, I start 过敏 in sixth year of stay in US.

I am fine in Maine for vacation. I guess when I stay longer in one area, if my body detect 过敏 resouce, I will 过敏 too...
