The 'So Long, Partner' meme is pulled directly from the emotional climax of Pixar’s Toy Story 3 (2010). In the scene, Woody watches his owner, Andy, drive off to college, marking the end of an era for the toys. Since its release, the image of Woody standing on the porch has become the internet's go-to reaction for heartfelt or ironic goodbyes. It is commonly used to express the pain of finishing a great TV series, leaving a job, or the universal struggle of seeing Sunday evening turn into Monday morning. The meme resonates because it perfectly captures that specific feeling of nostalgia mixed with the inevitable necessity of moving on.
