回复：请教各位大哥大姐孩子上大学交学费的事：

First, how the kids became citizen but the parents are not?

Second, you have more than one house and you expect sympathy from others who don't?

Third, if you have two kids in the colleges at the same time for three years, you are lucky.  You will pay about 130% of one kid's expenses for both kids.  When you are through the college payments then you are free.
