Weird Question about Harry Breaking a Mirror

[stacygalore]

I am writing an HP fanfic, and recently wrote a passage involving a student punching a 
bathroom mirror then sliding down the wall to the floor in tears.  Then I had a bit of deja vu.  
I thought, maybe, this actually occurred in canon.  Can anybody recall something like this 
happening?  Did Harry ever punch a bathroom mirror?  Maybe I just dreamed it, maybe I 
actually read it.  

Thanks,
Stacy
