Which character trait does the characterization from the passage above reveal about arnold

If the passage which I have found is exactly what you forgot to share, I can give you the right answer. 

I haven’t had a seizure in seven years, but the doctors tell me that I am “susceptible to seizure activity.” Isn’t that one of the worst phrases you’ve ever heard? Susceptible to seizure activity. Doesn’t that just roll off the tongue like poetry? I also had a stutter and a lisp. Or maybe I should say I had a st-st-st-st-stutter and a liththththp.

I am pretty sure that the character trait which is being revealed from the passage above is cynical attitude.
