Question: Why do we blush?

Answer:  We blush when we feel embarrassed about something that we have said or done. It is just one of the many physiological responses that we humans experience when we are feeling flustered.  Our body reacts very much the same way it does when we feel scared. It undergoes something called the fight-or-flight response. When this happens, adrenaline is released, causing our hands to get clammy, our heart to race, and our face to get warm and red. What is unusual is the mechanism by which our face takes on this rosy hue. It is the dilation of our veins that causes more blood to flow to our cheeks. The interesting part is that veins in most other parts of our bodies don’t react to adrenaline. Scientists have different theories about why we blush. Some suggest that it is to demonstrate to others that we really are sorry for our bad behavior or social blunder.


Attendance Matters!


•     Too many absences can cause children to fall behind in school.
•     Missing 10 percent can make it harder to learn to read.
•     Students can fall behind with just a few absences. 
•     Being late to school may lead to poor attendance.
•     Absences can affect the whole classroom.



Set a regular bed time and morning routine.
•     Lay out clothes and pack backpacks the night before.
•     Find out what day school starts.

•     Introduce your child to her teachers and classmates.
•     Don’t let your child stay home unless she is truly sick.

•     If your child seems anxious, talk to your child's teacher.

•     Develop back-up plans for getting to school.
•     Avoid medical appointments and extended trips during school time.

A Caution About Absences

The laws regarding truancy have strengthened significantly.  In addition to the EC penalties for parents in Section 48293, Penal Code Section 270.1 provides penalties.  Please note:

Section 48293, Penal Code Section 270.1 

A parent or guardian of a pupil of 6 years of age or more who is in kindergarten or any of grades 1-8, inclusive, and who is subject to compulsory full-time education or compulsory continuation education, whose child is a chronic truant as defined in Section 48263.6 of the EC, who has failed to reasonably supervise and encourage the pupil's school attendance is guilty of a misdemeanor punishable by a fine not exceeding two thousand dollars ($2,000), or by imprisonment in a county jail not exceeding one year, or by both that fine and imprisonment.
