Bad things, man, bad things
When you pull up to your weekender/investment property, and see water coming out from under the front door, that's not a good sign.
After we had been busily trying to spruce up the 1950s place for 10 months, it was under at least an inch of water -- an entire side of the duplex, save maybe a few-foot corner of the bedroom. A quick 7 hours of running two shop-vacs and mopping, and most of the water (except what was squishing up near the baseboards when you walked over them) could no longer be seen.
