This actually happened more than one, and seemed kind of subjective as to which rain storm would cause one or the other area to seep. I suppose we should be grateful that it wasn't the roof--and we are!--but the dampness in the Abyss led to me loosing a lot of keepsake stuff that was all in one box (pre-move it was stored on my folding screen) that I thought was placed out of harm's way.
I thought wrong.
The entire time we were in the Longview house I could not put anything on the floor towards that wall (good thing I'd planned on shelves in that area, anyway) and even things like the legs of my stool--sealed wood--were not 100% safe from the damp that just would. not. go. away.
Shows what happens when you give a room a watery name, right? Though I had other reasons for calling it The Abyss, originally.
More will be revealed...
