IMO, you give people TWO chances. If they fuck up once, they can call it a mistake, won't do it again, blah, blah, blah.
2nd time ISN'T a mistake. Off they go.
Fool me once, shame on you, fool me twice.....
Just find something else to do instead of dwelling on it today. Shop, watch TV, read a book, go for a drive - hell, fly to Vegas for the day. Just get off the computer and you'll feel a lot better
Once you get your head back on straight, you can deal with the legal issues.
