I've been volunteering with various community literacy agencies for years and years and years. Through their auspices, I teach ESL—English as a Second Language.

My very first student was a young man from El Salvador. He'd been a medical student in El Salvador until it dawned on him that he could make a shitload more money as an unskilled laborer in the Unites States. So, that's what he did.

It was an eye-opener, I'll tell you.
