Hey hey hey? Is there a little aunt who is staying at home? Are you kidding me? My sister-in-law is the same age as me?
My sister-in-law and I are in the same grade and class? Sister, can you not sleep in class? Sister-in-law, do you want something to eat? Sister-in-law, your teeth are so sharp. Sister-in-law, are you a vampire?
Sister-in-law, I seem to have fallen in love with you.
Sister-in-law, you said you were leaving? Goodbye, sister-in-law, I will never forget you. After all, you have existed in my life.
Or maybe, I will accompany you until eternity.
