The update on this is that we both kinda went to our respective corners and didn't talk about it for about a day. I think that she respected that I just wasn't on-board with this adoption. She eventually said that she understood where I was coming from regarding my concerns. And I do feel a bit relieved. I just don't feel like it's the time. I have no doubt that we'll revisit this again sometime, but for now it doesn't look like we'll be adopting this one.
