Ed,
I can hear the conversation now . . .
Ed: You know that Idea I had of building the 30" telescope.
Mrs: Oh, here we go again. Yeah, what about it!!
Ed: It would be a silly and impractical idea.
Mrs: WHAT!!!
Ed: You were right again dear, it is too big.
Mrs: Your darn tooting it's too big. You don't need it!
Ed: What was I thinking? 25" is plenty. Glad you woke me up to it in time before I went totally silly and built a 30" scope. What a mistake that would have been. I love you darling, you do know how to help me not make mistakes. I will only go to 25" then.
Thankyou Dear.
Mrs: Yeah! And not one inch over! That will teach you to listen to me next time.
