Come June, I will have been married to Bob 30 years.

I will have to pay the piper for all the bad things I have done.
自分のしてきた悪事の報いを、受けなければならないだろう。

I will have to retire earlier than my original plan because my wife is sick.
妻が病気のため、当初の予定より早めに退職することになりそうです。

I will have to take one day off tomorrow. Is that OK with you?
明日一日休み取らないといけないんだ。いいかな？

Come June, I will have been married to Bob 30 years.
6月が来ると、私とボブは結婚して30年になる。
