The following building products should have NEVER been invented. They don't last and make lives difficult.
1. Linoleum- cheap product. Bad idea. Ugly.
2. Sheetrock- see previous post. Good idea but why can't someone come up with a better, less messy and time consuming product.
3. Carpet- traps every disgusting smell and piece of dirt in the world. Cheap and comfortable but always ends up gross.
4. Formica- cheap (noticing a trend?), ugly and doesn't last.
5. Vinyl siding- bad idea.
6. Shutters on exterior windows that remain MUCH smaller than the actual window opening and are nailed to the exterior siding.
7. Wall paper- especially when used to cover moldy Sheetrock.
