noise annoys

yelling should be reserved for
-1) signifying danger (but only when the potentially dangerous outcome can be averted by the yelling)
-2) sporting events
-3) cheering after live performances (musical or otherwise)
-4) any other time you feel like it if and only if nobody else can hear you

honking should be reserved for
-1) signifying danger
-2) letting someone know that they have been idling too long in front of you at a red light

p.s. i think i need to get out of the city
