Poke and prod your sister, get her hopping mad, do whatever you want to her. Just never ruin her art project. Or you will suffer a fate worse than death. As exaggerated as the gif is, it is ironically pretty damn accurate when it comes to a sister's typical response to such a heinous transgression. So if you plan on being in the proximity of her while she's working, be forewarned, because any slights or mistakes could lead to a meltdown of Chernobyl-esque proportions. But ruining things isn't reserved for human siblings and family, even animal families have their clowns. So enjoy the best of these animal goofballs, though I wonder what their reactions are to their siblings antics. Time to turn on National Geographic.
