*** you open the pantry door (after placing a towel under the leaky spot) and immediately notice a very large puddle on the pantry floor, three shelves that no longer hold DRY cereal and cracker boxes but splattered and soaked ones instead, and a steady stream of water dripping from THAT ceiling... drip, drip, drip.
*** you assume a bathroom/pipe leak directly above and call the plumber, who in turn slices a hole in the kitchen ceiling to take a "peak." This, in turn, results in a gushing waterfall of sorts-- straight from kitchen ceiling to kitchen floor. Evidently = no minor leak. And this of course, inspires your favorite two-year old to happily proclaim, "Mommy, it's raining!" Yes... outside AND inside. What fun.
*** that same plumber climbs into the overhead storage space (in the adjoining hallway) and all you hear him mutter is, "Oh, wow."
*** you (along with the plumber) realize it's NOT a plumbing issue at all but a roofing one instead. So as a result, you call the roofer. Once he arrives, he carefully examines your situtaion (with a look of profound confusion on his face) and then slowly declares, "I don't know HOW that happened."
*** you then continue to hear words from the roofer (and his coworker-- the one he's since called to come join him in the search for the source of the leak) such as "puzzled," "I don't know," "I'm baffled," and "How on God's green earth did it GET there?"
Yep, that's when you know you've got a problem. A BIG problem.
Funny that I would know :)
