A: Schaue nach der Frage, um die Antwort zu sehen

A: Pi kikk! Im gonna leave now! Really appreciate for your kindness during Thai days! You made my days Kikk :)) if you have a time, i would like you to meet u again! Byeee
What do you mean by ‘Pi kikk!’ at the beginning. But other than that it sounds good 👌🏼 and are you saying goodbye to someone 😢

A: Pi unnie! It’s very kind of you to invite us over for dinner and for taking us out yesterday!
I’m not sure on what you meant in the end, but this is my best guess if Pi paid for your meal at a restaurant or whatever

A: Pi day is on March 14th, and it's to celebrate the number Pi (3.14). The reason it's on March 14th is because that date written in numbers is 3/14, the first 3 digits of Pi. My friends and I celebrate by eating circle shaped desserts like cookies and circular cakes! Pies too, of course.
