There are new experimental ways to teach your children, but the following should be banned because it’s nasty. A teacher in Norway was coming back from the doctor when she asked the nurse to take a vial of her blood to go. When she got to her class, she poured it on a plate for the children to see.
The children asked if she could touch it and she let them. Then they asked how they were supposed to take it off and she put her finger in her mouth and the children followed suit. The teacher has apologized but obviously already been fired. This teacher has terrible judgement! The blood has been sent to be tested for AIDS and Hepatitis B.
