You have to really respect what your kids are doing with their kids and how they're raising them. You can't push your way into areas where you shouldn't be saying anything. You have to always remember they're not your own kids. Play with them, love them, spoil them to death - then hand them back.
You don't want to really pick on someone that you genuinely like. In terms of 'Billy on the Street,' there are certain actors - I don't care if they find out because I do feel that way. Though it's almost never about appearance or something out of their control. I pick on choices they've made or roles they've taken.
