Then you are probably quiet, shy, and you would rather follow than lead. You tend to be pessimist. At least,

and a red dress brings warmth and cheer to the saddest winter day. 4_____. A black bridge over the Thames

River, near London, used to be the scene of more suicides (自杀) than any other bridge in the area-until it was

repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even

more if the bridge had been done in pink or baby blue.
