君、ええ仕事をしてるな。

You're doing good work there.

君、本当に企画通ったこと確認しただろうね。糠喜びだけはごめんだよ。

Are you saying that our plan was accepted? I hope you're not showing me any premature happiness here.

駄目だよ。君、背が高いんだから前衛に来てくれないと。

That's no good! You're tall so you've got to be in the forward defence.

ふたりでまじめな話をしているんだから、君、無責任な横槍を入れないでほしいんだけど。

Hey, we're trying to have a serious discussion here so I'd appreciate it if you wouldn't butt in so irresponsibly.
