If a forty ton Bulldozer crashes in to your house and you're homeless ! Does it mean you come from a broken home ?

Ok.  I'll buy that.  But what about if it is a 20 ton bulldozer?  Same?

What if it is a 5 ton?  Perhaps you can just downsize to a junkyard.  

I would say shattered dreams and a broken home

I once had a buddy destroy an old shack that was on my property. He used a 'backhoe' type tractor. Ripped it to little pieces. Then some guys who needed firewood came and hauled away the wood, leaving a small pile of roofing shingles. You don't need a 40 ton bulldozer to tear apart a standard wooden home. A backhoe and some GRRRRR  attitude can do the job.
