Like Jombo said, at this point I can't trust you; this is a serious matter, and you've had the first chance to own up to all of it, but you've chosen conceal it.
I'd have been more forgiving of it if you've owned up to it all of this when you were first questioned, but now with more stand in proof, it's pretty much sealed the respect you've lost from me.
I'm dissapointed entirely.
