早速本題に入るけど、飲み会の件なんだ。今週の金曜日あいてるかな。

Anyway, to get to what I wanted to ask you...it's about the party. Are you free Friday?
私たちは、これまでささいなことを話し合ってきた。そろそろ、本題に入るころだ。

We have been discussing minor matters; it's high time we began talking turkey.
最近、気づいたことがあって、普通メッセージの最初にHelloとか書いてから本題に入ると思うんだけど、なんか、いきなり本題に入ってそれだけで送る人も意外に多いのよね。これってどうなの？

Something caught my attention recently. I usually say hello or something similar at the start of messages before moving on to the topic of the message. But, surprisingly, I've seen a lot of people dive right into the topic and send nothing else. What's up with that?
