 The only rule is they are allowed to waive if they've served once in the last 12 months. Yeah, but like back to back years. So, yes, like if his number gets called up in 2022 and then he serves and then he gets called up again in 2023, he can serve again. I just can't wait for the first one that says, come on, get some new material because they've heard it the first time. But it works for you, right? And you want to be if it works, you got to keep using it.
