 And let's give out our phone numbers, Mark. And then I wanna talk about a similar problem to Gail's that we've solved a solution on. It had to do with one of the most common dust problems. We're gonna talk about it. She actually reminded me of a similar problem that we had so many people have, that line of dust that is on your staircase, right at the bend of like every stair with your carpet. Everybody gets that line of dust.
