Carmen asked Michael for a definition of PWP. Given the context in which his used the term it was not clear to me either. I believe in the singular PWP stands for Person With Parkinson's and in the plural it means People With Parkinson's.
To have some fun on a wet Friday night I took the three letters and decided to play around a bit and see what I could do. The following is a result of that effort. I caution you to not search for deep meaning in any of them and remember this was done quickly. I challenge all you word-smiths out there to come up with some really clever and meaningful examples.
People with Parkinson’s
Pissed-off with politics
Pontificate with purpose.
(Perturbed could be used for Pissed-off)
Parkies whisper poems
Prepared with passion.
Parkies wail parables
Prepared with poison
(I don't like this one but I left it in anyway)
Parkies who party
Party wildly perpetually
Partners with patience
Pensively wonder purpose
