Sick kids
Why in the world would you send your kid to school when you know he is sick????
One of mine today puked IN my classroom within about 20 minutes of the day starting. In the middle of the mid-term. Turns out, mom knew he was puking and still sent him. Nurse had to explain why that's not allowed. They claimed they were worried about missing the test. But my kids know I always let them make-up tests they miss.
Now I have a bunch of kids who were too distracted to take their test properly. And we've all been exposed to whatever he has. Plus the poor kid is probably embarrassed.
