"things" can happen. Children tend to be disruptive more with friends and disrupt the other classes. Also when the teacher is gone it is a good time to do your homework so you don't have to do it at home or at least not as much. So this is just a few reasons you should not get up in class.
Herpes simplex is a viral disease caused by the herpes simplex virus. Infections are categorized based on the part of the body infected. Oral herpes involves the face or mouth. It may result in small blisters in groups often called cold sores or fever blisters or may just cause a sore throat. Genital herpes, often simply known as herpes, may have minimal symptoms or form blisters that break open and result in small ulcers. These typically heal over two to four weeks.Tingling or shooting pains may occur before the blisters appear. Herpes cycles between periods of active disease followed by periods without symptoms. The first episode is often more severe and may be associated with fever, muscle pains, swollen lymph nodes and headaches. Over time, episodes of active disease decrease in frequency and severity. Other disorders caused by herpes simplex include: herpetic whitlow when it involves the fingers, herpes of the eye, herpes infection of the brain, and neonatal herpes when it affects a newborn, among others.
My calc teacher literally leaves class for 10 minutes at a time no joke and we all sit there and we all want to stand up and stretch but we aren't allowed. I would say high school students should be allowed because most of the are mature enough to know right from wrong while elementary/middle school students aren't yet.
