E-mail from Heaven

One midnight at 3 am, I heard an email sound coming from my.....dead father!? A long time ago, when I was a kid, my father died because of a disease called chronic kidney disease, leaving me & my old, gorgeous mother whose worried about my father's death. 10 months has passed when my father died. I was working with something when suddenly, I receive an email coming from my dead father. I closed the laptop & never used it again. Times has passed & I decided to read my father's email which includes a mission for my mom. It has been said that it was a secret for my mom because in the email title, it says "DONT TELL MOMMY". I recognize that it might been a surprise for my mom. So I decided to listen & read the missions that has been needed for surprising my mom.
