We overestimate each other about what we know, and how the assumptions that we make. And then what it does is sort of compounds on itself. You assume that i must know that so in my and if i don't know it, i have to pretend to know it and assume that everybody else in the room knows it. I think part of it is just good old sometimes we just, we, iis literally just blind to it. We're all so proud we like to talk about things that are complex, that are impressive. But when you go down to where were it were assuming things, oftentimes those can be the richest conversations yes.
