I feel happy each time I see in-laws getting along and I must commend your brother's wife for her self control and confidence.
Nevertheless, your inner circle are great personalities and permit me to quote about your fellow student.

One quality I love about her is "Godfidence". I call it Godfidence instead of confidence because I'm actually referring to the boldness one possesses in God.

I will soon start using Godfidence on some people.

Best of luck
