Today we went over the Ch 16 test. We will be skipping to Ch 19 next in case you want to start reading and doing the vocab.
Ch 19 will be the last chapter for the semester.

If you are reading this, you may be interested to know that next fall Byng Schools will have a new interface for the school website.

I have been testing, reviewing and assisting with the implementation of the new system. Hopefully it will be an even better tool for communication between the school, families and community.

Male modesty not appreciated by female or male interviewers, study suggests July 31, 2010
A researcher who explored the consequences for men (and women) when they acted modestly in job interviews found that "modest" males were less liked, a sign of social backlash. Modesty was viewed as a sign of weakness, a low-status character trait for males that could adversely affect their employability or earnings potential. Modesty in women, howe […]
