>the shingles, and tar paper are peeled up exposing the plywood underneath
>there's a half inch gap between the sheets of plywood under the tar paper
>she says, and I fucking quote "Just use some flex seal"
>not the paint shit, the spray on kind.
>say that shit isn't going to work based off of common sense
>did i mention she's 60 years old?
>how in in the blue hell does she plan to make that shit work? She sure as shit isn't going to use anything but flex seal.
>she's had stupid ass ideas like this before. From saying "i'll just insulate the basement with cardboard stapled onto the fucking rock wall. (we live in an older Victorian home) and sure as shit, it didn't work. And she blew 40 fucking dollars on cardboard.
how in the hell can i talk some sense into her? Nothing gets through her fucking head. And if i actually present evince to support my claim, I get called a "smart ass" and "know it all"
