YOU SAID:
Been about three days and I'm coming back
INTO JAPANESE
約3日経ちましたが、また戻ってきます
BACK INTO ENGLISH
It's been about 3 days, but I'll be back again
INTO JAPANESE
3日くらい経ちましたが、また戻ってきます
BACK INTO ENGLISH
It's been about 3 days, but I'll be back again
That didn't even make that much sense in English.
