Input: Text: i mentioned this story in another tifu and someone asked for the full story.

this occured the summer that my older sister got married. she and i have never gotten along. i wasn't over the moon excited about her wedding because ~~she and her now-husband had slept together while he was still dating me~~ it's complicated. not that i don't adore my boyfriend but it was still a touchy topic. 

she and her then-fiancé were living at his (small) apartment so my parents' house (where i was still living) was sort of the staging area for all of the stuff.

she had chosen this gorgeous and uber-expensive dress with this beautiful lace bodice, and it was hanging in the closet in her old bedroom. now what you have to understand is that after my sister left for college, we started using her room (especially her closet) as a storage for random things like ironing board, extra suitcases. her room is big, so the extra stuff never really bothered her but she never really loved the idea of us going in and out of her room even though she had moved out.

like i said, my mom had it hanging in the closet. there was a sheet loosely draped over the top but it left the bottom foot of the dress exposed. 

this is where i come in. i was seriously sick with a high fever and i got up around 4 and really needed a blanket. so i stumbled next door to my sisters room to grab an extra blanket from her closet. i didn't even turn on the light.

i open up the closet and the blankets are stacked on the high shelf while the dress is taking up the space below. it's at this point that i feel vomit rising up my throat. but in a lucky turn of events, i see an empty rubbermaid shoebox on the floor. i drop to my knees and immediately vomit into it. then i take my box and blanket, dump the contents of box into the toilet, vomit again, and go back to bed. 

next morning i wake up to my sister standing over me looking like she wanted to stab me with a plastic hanger. apparently some of the vomit had escaped the box, and had spent three hours fermenting in her closet next the bottom of the wedding dress. 

she was furious. she didn't think i had done it on purpose but she was incredibly incredibly pissed. she was worried about the stains but the smell too.
