A war that took place between two sisters, age 9 and 14. It happened while their mother was at work, and uncle was on the back patio. This is why you should never leave us kids alone in the house. Needless to say, there was a large mess afterwards, and they did not clean up as well as they thought they did, as today, Wednesday, May 15th, 2019, they discovered the leftover missiles (jelly beans) under the couch and in the cushions. Their mom only found out today, when the 14 year old opened her mouth and spilled the beans about the war that even their uncle knew nothing about.

ps- I really need to learn to keep my mouth shut when it comes to things that can potentially get me in trouble...

An angel named Lillith went down to the human world a lot and soon dud fall in love with a man. Then after a very long time the man got sick and was about to die, then she took some food from the Celestial Relm and gave it to the man, to expand his lifespan.
