So I came home today to find my sister crying and my mother sulking upstairs in her room.

Apparently, they're not on speaking terms because Cristalle denied her peanut brittle.

Mum likes instant gratification.  Cristalle, on the other hand, likes to hoard her food and savor it slowly--so slowly that much of what she has expires before she even gets to it.  You can see how there would be a problem. 

My family is amusing.
