Arigatougazaimasu Sugoi obenkiyou narimashita. Thank you really appreciate you hard work . :)))))))))))) uresiii desu

例文１ お母さん「あら、お醤油がもうないわ、スーパーに買いに行かないといけないけど今私忙しいからどうしましょう。。。」"We are out of Soya sauce, someone needs to get it but I am busy now, what to do...." 私「あ、じゃあ私が行くよ」"No problem, then I can go" In this sentence, Japanese native do not use 「私は」because 「私が」contains the meaning that several people can go but （out of several choices) I will do it in this situation. 例文２ お母さん「お父さんもう行っちゃったよね。私にも一緒に行こうって言ってたけど、私は行かないわ。」Your father has already gone. He asked me to go as well but I am not going. 私「あ、そうなの。でも私は行くよ。」"Oh really? But I will go" In this sentence, only choice is 「私は」as we have nuance that, you do not got but I will go regardless. Happy study :)
