"One I can't wait to read & to watch when my time comes." "It doesn't make sense though dude. It doesn't make sense. Maybe when we wake up tomorrow you'll be there laughing saying it was just a satirical short film you made. That it's not real," Woodley concluded. In a separate post, Woodley wrote, "You celebrated us women through our thickest & thinnest moments. you were there. you always wrote back, called back, texted back … immediately. no matter how busy you were," later adding, "Saying you will be missed is a massive under statement. you gave the world, and my tiny world, the treasure of feeling less alone + more alive. we will miss you everyday. thank you for being the artist so few of us can claim ourselves to be today: authentic, dedicated, well crafted, and true. I love you. transition beautifully ma chérie."
