Thanks for the response, RedneckDyke.
Mom used to do volunteer work with immigrant organizations. For example, for awhile she was a volunteer teacher for ESL (English as a Second Language). In one class, she had a bunch of Vietnamese people, and she joked that if you run into any Vietnamese people with German accents, they're her students.
We live on the Canadian prairie, which is famous for its harsh winters. Every winter we get a couple of 40-below spells. (BTW, 40-below is the point on the thermometer where Farenheit and Celsius match up.) Once a Vietnamese fellow asked Mom, "How can it be so bright and sunny outside and still so cold?"
