I go for her clothes. Dresses, sweaters, and shoes she hasn't worn since seventh grade are placed into garbage bags. I am a plague of locusts emptying the closet. Two piles grow to clumsy heights: one for charity, the other trash.
求教，后两句怎么理解啊？

One pile of clothes will goto charity, the other, goes to the trash bin.

一堆捐给慈善机构，另一堆扔掉。
