Input: Text: first post, so here goes...

let me start by saying how much i hate when my sister has friends over. she's in those pre-teen years where she has to look invincible in front of her friends. slightly unrelated, but today she had a friend over, and god did they (mainly she) piss me off...

first up, i'm sitting in my room, watching random youtube videos on my laptop. i get up to go to the bathroom, and leave my laptop open on my bed, next to my cat (my cat loves me/my bed. not sure which.) so as i finish up in the bathroom, i enter my room just in time to see my sister sit down next to my cat. on top of my laptop.

now she's not fat by any means, but a half-inch thick ultrabook is not supposed to take 50-odd kilos of weight, especially not on the edge of the open screen. needless to say, even my sister, with her extremely limited knowledge of computers, could tell that it was way beyond repair. screen shattered and completely separated from the keyboard, she bolts out of the room, leaving a very stunned friend with a furious me.

second time, about half an hour later while i'm discussing the laptop situation with my parents, i'm looking with a certain degree of loathing out the window to where my sister and her friend are mucking about in the garden. sitting on the trampoline is a parrot. now, i don't really take special notice of birds in our backyard since my sister started hand-feeding the kookaburras, but i probably should have done something about this one (not that i knew what was about to happen.)

anyway, my sister decides she would show off some trampoline tricks. as i've said, she hand-feeds most birds coming through our backyard, so they're all pretty comfortable around us. anyway, she gets up on the trampoline, facing her friend. and jumps.

apart from the whole dead parrot problem (which has traumatised her pretty badly), i now have a $1700 pile of wiring and other parts which are completely useless. she owns pretty much nothing, and is too young to work, so there's the issue of a replacement to sort out (pretty sure sitting on it voided the warranty). it's like sueing a homeless person; you'll win, but you won't win much.

TIFU (my sister did) by being uncoordinated/ignorant/stupid. Twice.
