Oops
When I was a pre-teen (aged 10, 11 and 12) there was a girl up the street from the grammar school who would come in to look after me and my brother when my parents would go out.

One evening the parentals were out and I was playing in the garden; came into the house through the kitchen door to spot my babysitter being (what I now recognise to be) "done" by her boyfriend who I didn't recognise.

I screamed like a baby for a few reasons most of which being that I didn't recognise the bloke in question and in my imagination the house had been broken into and my babysitter was being attacked.

With my imagination running in over-drive I jumped on the back of babysitters boyfriends back and using my "fists-of-fun" started thumping him, thinking I was being a knight in shining armour.

Much, much embarrassment all round but I didn't tell my parents and babysitter kept coming around.

Postscript: many years later, she ended up marrying the boyfriend and the last time I heard (last Xmas) she and he were still married and has a thousand kids.
