There's no doubt it was not accidental. My gf forgot where she put some of the files on her computer and for some reason decided that I'd deleted them. So, what did she do?...
Yup deleted some really important files from my computer.
Sometimes they just need more attention, (the gf's not the puter) Whatever you do don't crack, it's all part of the female testing procedure to see if she can trust you. If you remained calm then you passed the test...todays test that is. There'll be another one tomorrow.
