 All right, let's go to Wally. Wally, welcome. Hello there. I'm a 78-year-old contractor who today is bending up aluminum to put on the windows Monday. Love what I do. And I have two quick questions for you. You just can't, once you do it, you can't get it out of your blood. Yep, I hear you. First question is, a lot of times I run the drain, especially in rehabbing places, and I want to put something in them.
