 So, Leslie, I'm thinking that with flagstone being an irregular surface like that, I've seen people try to fill these cracks and spaces between with mortar, but it never works out because it's not designed to be that strong. Well, no, and I always feel like when you have mortar in between flagstone with the Friesenthal cycle, it just cracks out. Yeah. Unless it's like a fully installed patio on top of concrete and you're controlling that. Yeah.
