In a sense my tremor sends out advance warning that there is something different about me. I only arrive as a person (and not as a disease) after the tremor has set up initial communication. Other people are free to greet my tremor as me without noticing the marching band playing the music of who I am, which accompanies my later arrival. This is an inevitable risk of meeting new people: others might judge me or reject me based on my symptoms. However, that “might” includes a “might not”; others may see me alongside my symptoms.
The only way to eliminate the possibility of rejection because of Parkinson's is to hide yourself away, therefore discarding the possibility of acceptance; thus, rejecting yourself before anyone else can.
Anyway, why would you want to spend time with someone who only sees your symptoms?
