I am reading a book in German and have come across an expression that I can't understand (to be honest I have trouble understanding the entire sentence). The book is called "Das also ist mein Leben" and the expression goes like this:
Es ging offenbar darum, wie er mit fünfzehn mal vor dem Klassenfiesling eingeknickt war oder so was.
My guess is that the sentence is about a boy forced to kneel down 15 times in front of a bully. But then again why would we use 'mit' instead of leaving it out?
