Four years ago:
Me: Hey, wake up!
Sister: It’s 6 am! Go away!
Me: No! Wake up! I really need to finish this homework.
Sister: Then finish it.
Me: I’ve been writing most of the night. I have more difficult diagrams to draw. You just have to copy the text I give you.
Sister: No way! Go away! I need to sleep! I came in late from work last night.
Me: I know! I won’t bother you again. Please?
Sister: (Sigh and get up) Fine. Just this once.
Brother: Sister, I need your help.
Me: (Look warily at the clock. 11pm.) What is it?
Brother: Just copy these pages in this classwork notebook.
Me: No way!
Brother: Please! I need to finish this! I have a lot to study.
Me: It’s late and I’m tired!
Brother: I know! Just this once! I won’t ask again.
Me: Ugh.. fine. What is it.
Four years ago, 1 day later:
Me: (whisper) Are you sleeping? (Poke)
Sister: What now?!
Me: (My prettiest smile)
Brother: Where is my dear sister?
Me: Oh. My. God.
Brother: (Devious smile)
Four years ago, I must have known.
