NextLine - it hadnt recived that much abuse, it was 4 or 5 years old probably but there were no (visable) cracks prior to this. It had just been used as a table. Nobody ever fell into it or anything like that.

Slip - Thats another good possibility i guess, there is alot of activity in the sky (its nyc for christsake) and i guess a small bolt or something could have fallen and broke it. the only thing is we had the umbrella open and i didnt have a chance to double check it yet but there would have to be a tear, also the house would have blocked anything falling from and angle on one side.

i knew i shouldnt have but we cleaned everything up right away and not to mention it was garbage day so that bag of glass is long gone, theres no way we could find out if there was anything out of the ordinary in the debris.
