i learned this from being a young skunk addict. in my late teens i realised that every conversation has a subtext comprised of insult and mockery and attack. that because language is artfully ambiguous (and this is the whole point of finnegans wake) it can embed multiple meanings in the same phrase.
and if you develop an ear for it you will know that friends and family as well as strangers, are tearing shreds off one another all the time. which is why i like the hashtags here because it's a kind of literalisation of that... the composed superego and ego above the line and the snarling, thrashing (and very funny and truthful) id beneath it.
where you can run into serious problems is when you take that hidden id of any conversation, that hostility and scorn, for the only true reading of the text, or even just as more real, than the love and camaraderie and support which is also present and also very real and true.
yeah this is why i got addicted to skunk as well. now that i live with my mum and dad again i still can't explain to them that feeling.
