Is it rare for a parent to report their own child to the principal's office?

Well almost and it's not something I'm proud of. 2 years ago (then 14), my parents somehow found out about my behavior towards someone else.

My father is a child psychologist himself and mom is a grade and middle school teacher. Yet, I underestimated it all and didn't think they would take this seriously enough to nearly report me (that would've meant a suspension for me) themselves. It was followed by withdrawal of attention (they had a very disappointing expressing, barely speaking to me), a longer grounding, cell confiscated, limited access to Internet, them speaking with the other student and them walking me to class and picking me up from school (not letting me take the bus) for a longer time; quite embarassing. Usually dad isn't too much into longer grounding but he agreed with mom on it; the only he wasn't on my side either.

Now I know they wouldn't cover up for me if I'm 100% in the wrong. Are parents like mine rare?
