Another example ,
2) When someone finishes PTA members of committee,
Ms. A, Thank you for your support.
Ms. B, Otukaresama-deshita.
Thus, in this situation, Otsukaresama-deshita means “You did a great job!”
And “Thank you so much.”
When someone finishes a project, he or she often uses this word.
I recommend that you remind “Otukaresa-deshita”, because the word
is very useful.
“Gokurosama-deshita” has a similar meaning, but you should not use it
to people who are senior of you.
