Ah, well, you know, that door... ummm... single 
glass, no real frame, just one damn rectangle of 
glass... it's easy. a) be VERY pissed, b) don't 
care about anything anymore, c) slam the door 
shut with all the force your (over)weight can 
create...
But no, I wasn't hurt :) I have my experiences 
with glass though... like, beating through 
(single glass) windows when pissed, or breaking 
through a horizontal window covering a hole in 
the ground with bare legs... ahaha...
