me and the wife were very volitile when we were younger mate .
we were coming home one night and having a row as you do and i hit the windscreen in frustration and the this just cracked every where lol ,it was her first car , a mk1 fiesta.
i had to take it to autoglass the next day to get a new screen and they broke 4 screens trying to get them in because of the rust around the frame , almost wrote it off.
she still reminds me about that to this day , and that was nearly 20 years ago.
