I have a really strong memory from infants, when I was 5 or 6 (so about 28 years ago) of us having to do a 'Science Experiment' in class. Our teacher was a female and seemed elderly to me at the time but was probably actually in her 50s.
The experiment was to find a partner and then touch tongues with that partner. I chose my best female friend and I don't know if anyone chose a member of the opposite sex.
Looking back it seems really weird, I can't imagine why we had to do it, and everyone I tell about it looks at me like
. It's not a false memory by the way - I know it definitely happened!
Did any teachers ever make you do anything like this?
