Useful tip. Buy a trumpet instead of yelling.
Blow it very loudly. If you make beautiful music, then you have accomplished something. If you make an awful sound, someone will eventually come and ask if you are o.k., then you can tell them why you are making an awful noise. They might even sympatise with you, just to get you to stop blowing the thing, or they might pull out their trombone and you can both make a terrible noise. Never know you might end up with a whole brass band, then a politician is bound to turn up or the media and you can tell them your reason for making a terrible noise. Of course attempting to play something patriotic with a flag in the background, might even get you on t.v. and you can have your 15 minutes of fame to air your feelings to the whole world.
And all this because you blew in a trumpet, amazing ay
