Boromir had a long sword, in fashion like Anduril but of less lineage and he bore also a shield and his war-horn. 'Loud and clear it sounds in the valleys of the hills,' he said, `and then let all the foes of Gondor flee!' Putting it to his lips he blew a blast, and the echoes leapt from rock to rock, and all that heard that voice in Rivendell sprang to their feet. 'Slow should you be to wind that horn again, Boromir,' said Elrond. 'until you stand once more on the borders of your land, and dire need is on you.' `Maybe,' said Boromir.
this is funnier every time i read it
the way this is written there is no impetus for boromir to describe and blow the horn. i am picturing that 'off-screen' so to speak, maybe pippin or somebody pointed to the horn of gondor and said 'hey whats that' and the answer was OH ITS SUPER LOUD ITS TOTALLY SICK LET ME SHOW YOU FWEET FWEEEEEEEEET but maybe that didn't happen and boromir really did this with zero provocation.
everyone in rivendell freaked out
'friendo, do not blow that thing again until you are back in your own country, and even then, it had better be dire'
'Maybe,' said Boromir
