Hi Bro, Hi Sis

Hi, sis, long time no see.   We used to be roomies.

Remember me, sis? You loved my furnishings so much that you ate them.

Bro, I don't want to hear it, I don't want to look at you.

OK, sis, I won't talk about it again, I apologize.

Bro, I forgive you.  We are good brother and sister.
