*Congratulation someone for two issues! :)

Thanking someone because of two issues. Example: تبریک دو جانبه هم بابت تولدت هم قهرمانی تیم محبوبت My bad translation: A "tow sided Congratulation"!!! because of your birthday and the championship of your favorite team! Albeit "tow sided Congratulation" almost surely is not a good translation!

Thank you so much

when two people greet each other at the same time

mutual congratulation
