Haha, yeah. A 'shower door window', there we go. I don't know what else to say. What I told him is what all of the suggestions I read combined together were. Basically, defect+deterioration+some other things...Yeah.
Steam would deteriorate tempered glass over a while? Whoa.
Oh, oops. I failed to mention that this wasn't a 'window' window...Its the glass in a shower...I can't explain better. It was like the picture below only not as fancy. It was also sliding instead of on hinges.

Well if it helps, I thought of the settling house theory. Then I found out that the glass nor the frame touch the cieling. Would it be possible that one wall moved inwards causing more stress on the glass? Btw, you guys are fast at responding, lol.
Thanks guys for all the responses. Yeah, only two ppl live in that house. My friend who was on the phone playing his guitar in his room...and his mom who was in her bedroom on the bed. No one else was in the house. The crack was vertically straight down the center.
I was recenlty on the phone with my friend who moved into a new house. The house has been around for a little while...nothing too long. He was on the phone when his mom told him to hang up and look at this. As it turned out, a pane of glass in the bathroom shattered. He looked at it and watched...
