The friendship assisted living facilities were established by Twilight Sparkle in 2002 because there were not enough facilities for helping ponies with disabilities, usually ponies with disabilities were locked away in big prison like houses.

But Twilight and her friends felt it would be better if disabled ponies were able to be free.

Pinkie liked the idea so much that she volunteered for a job.
