YOU SAID:
Your father left to get the milk
INTO JAPANESE
あなたのお父さんは牛乳を取りに行ってしまいました
BACK INTO ENGLISH
your father has gone to get the milk
INTO JAPANESE
あなたのお父さんは牛乳を買いに行きました
BACK INTO ENGLISH
your father went to buy milk
INTO JAPANESE
あなたのお父さんは牛乳を買いに行きました
BACK INTO ENGLISH
your father went to buy milk
That didn't even make that much sense in English.
