Is it a bad sign if...
...you walk past the kids' bathroom and water puddles up around your feet through the carpet?
... or if you then try the bathroom door and find it locked?
... or if, in a moment of sudden quiet while your lovely visiting teacher is praying for you, you can hear water running in the ceiling above you?
... or if, when you open said bathroom door and find an inch of standing water covering the whole bathroom, you ask your 4-year-old what happened and he says there was a toilet paper monster trying to escape from the potty?
... It may possibly be a sign that a certain 6-year-old, who shall remain nameless, tried to be helpful and gather up the huge pile of toilet paper spun off the roll by a passing 17-month-old and flush the TP down the toilet. It's also possible that said 6-year-old freaked out when the toilet started flooding, locked the door so his mom would never know, then ran off to school.
Ah, the life. 15 soaking towels, an hour of stomping the wet carpet, and a big bulge in the paint on the wall of the kitchen later, the jury's still out on this one...
