Hello!
I have A-B-C for you to remember.
watashi wa anatani A - B - C o tsutaetaidesu.
A- always do your best of whatever you do.
Anata ga nani o suru ni shite mo, tsuneni anata no besuto o tsukushi te kudasai.
B - be brave and laugh at your mistakes.
Takumashiku soshite jibun no misu mo waratte fukitobashi mashou.
Keep the learned lessons.
Mananda oshie mamorou.
C - care of yourself and the people around you.
Anata jishin to anata no mawari no hitobito wo taisetsu ni shiyou.
Spread kindness.
Yasashisa wo hiro ge you
Lastly, Please study hard! Not just English but all your subjects.
Saigo ni, isshōken mei benkyō shite kudasai! Eigo dakedenaku, anata no subete no kamoku mo.
But really, please study English.
Shikashi, hontōni eigo o benkyō shite kudasai.
So, we can speak in English when we meet in the future.
Sōsureba, watashitachi ga shōrai atta toki ni eigo de hanasu koto ga dekimasu.
And, I don't need to ask Ms. Nishimae or goggle to translate.
Soshite, Nishimae-san ya gūguru ni hon'yaku o irai suru hitsuyō wa arimasen.
