One synesthete, a woman named Veerle Provoost, would often board the wrong bus because she interpreted the colors of the bus incorrectly. (In Bruges, Brussels, buses are color coded to facilitate traveler identification (van Campen 66).) Earlier, a blind man who had developed synesthesia was mentioned; his case of touch-sight synesthesia was incredibly severe, and the images were frequently "intrusive." This blind man's case of synesthesia ruined his Braille reading ability, effectively preventing him from reading information portrayed on signs, et cetera (Ramachandran, Blakeslee 298). There is also an apparent social stigma that goes along with synesthesia; many people believe synesthetes to be lunatics, and the trodden-upon synesthetes often become reclusive. Once these synesthetes become reclusive, they will rarely share their experience with the scientists who study synesthesia (Cytowic 119).
