That’s true / You’re right / Showing agreement (そっか / たしかに / まあね)

As always, the nuance in Japanese needs me to document this down.

• そっか – also means I understand you, shows empathy
• たしかに – had different opinion, but now I agree you’re right
• まあね – subtle agreement, may have a slightly different opinion, but don’t want to say it aloud

A: 今日、パスタ食べに行かない？
B: うーん、パスタか… 。昨日も食べたんだよね。
A: そっかー。
[A immediately understands and acknowledges B’s reason for not wanting pasta (ate it yesterday).]
B: じゃあ、和食は？OOOの定食、美味しいらしいよ。
A: 和食か… 。ちょっと高いんだよね、あそこ…
B: あ、そうだった？ランチは手頃な値段って聞いたけど。
A: たしかに、ランチなら大丈夫かも。夜は高いけど。
[A initially hesitates about Japanese food due to price. B provides new info (lunch is cheaper). A uses “たしかに” to agree with B’s point about “lunch price” specifically, shifting from initial price concern to accepting lunch as an option.]
B: よかった。じゃあ、和食にする？
A: まあね、和食もいいね。たまには。
[A agrees to Japanese food, but “まあね” and “たまには (tama ni wa – once in a while)” show subtle agreement. It’s acceptable, but not a passionate “YES! Japanese food!”.]
B: うん、そうしよう。
