TIFU By repairing my professor's iPhone My professor came to class complaining that he'd just broken his screen.  I volunteered to repair it (it's something I do on the side).  I've done over 20 repairs and never had even a minor issue.  This time, the screen doesn't turn on and I cracked the new screen putting it in.  I see him tomorrow and he'll ask how it's going FML.

TL;DR: I owe my professor a new iPhone 5s by tomorrow.
