I think he asked me because he didn't want incomprehensible garble that Google translate blurts out...
Translation: I went to the Post office today to send a thank you letter to my mom, because she sent me some fruit♪ The Post office's Pelly had previously worked at the town hall, although it wasn't with me (**Shizue is clearly talking because of this distinction). Pelly always has a smile and works hard. I hope that I can become like her someday!
Thank you!
