I can sleep in for a week, but my great granddad wont allow me to do it
INTO JAPANESE
私は1週間寝ることができますが、私の偉大な祖父は私がそれをすることを許しません
BACK INTO ENGLISH
I can sleep for a week, but my great grandfather won't allow me to do it
INTO JAPANESE
私は1週間眠ることができますが、私の偉大な祖父は私がそれをすることを許しません
BACK INTO ENGLISH
I can sleep for a week, but my great grandfather won't allow me to do it
That didn't even make that much sense in English.
