A Laugh Just before Bed

It was past twelve midnight and I switched the room lights for bed. My aunt was giggling, she told me she just recalled bed times when I was younger. I asked, so what's it about? The giggling begins then. Remembered the time when your sister, you and I used to sleep in the same room. You said "Ghost" "Ghost" whenever your sister off the lights. You always shout that the "Ghost" will come and catch you. Then, your sister yelled at you and a quarrel begun. That was the story and I started laughing but need to control the volume. Goodness, the silly me once a upon a time. Lights off and "Ghost"!!! Haha...
