We went to university together buy ropinirole Stewart is 55, tall and thin and animated. At work he wears a clip-on tie, a white cotton shirt with a fraying collar and a pair of black sneakers he nabbed on sale for $12.99 a few days ago. He wheels elderly air passengers from the ticket counters through security and to their gates, and back again, and every once in a while they tip him. Usually for lunch he buys a candy bar. His skin flakes from psoriasis, which gets worse when he worries, which, these days, is all the time. He can’t pay for treatments to soothe the itching or for a car to shorten his predawn commute.
