Language itself is the problem: to express your feelings to others, you need to work around an incredibly inaccurate and imprecise framework of sentences, forcing your emotional state at the time into a series of verbs, adjectives and nouns. Without the bonus of body-language, eye contact and so-on that give greater context during communication with other people, it's difficult to be understood properly.
I find that the English language, and other languages, make expressing yourself sometimes exasperating because even though, undoubtedly at some point during history, the word that describes your feelings best is within the confines of the language, I am incredibly inarticulate and I've the greatest trouble making my thoughts known to anyone. Studying language was never a waste, but it has not helped me on that front...
Still, if it's literal, and the poet is discussing people who lie, then I agree somewhat with mrflowers00's short and to-the-point opinion. However, a great deal of people lie because they have to; the guy or girl taking your order at, say, Burger King is not pleased to meet you or happy to see you in any way because they more likely than not don't really give a fuck whether or not you exist; it's just practised common courtesy to be greeted by a person in a restaurant or a shop, wearing a smile, and you might talk to them or treat them like a wanker, but ultimately your mood decides how nice you can be, whereas their manager decides whether or not they're being kindly enough towards you!
People have to lie, and without lies we'd run into a lot of trouble. Scandals are on one hand awful, but also fun: we've learned over the past century that our leaders - our presidents - are capable of lying like us wee mortals and it's both sad and frightening; such people ought to be superhuman! You won't get mankind to drop lying any time soon.
mrflowers00: Is there anything in particular, or some specific event that caused you to think of this? I'd like to know why you decided to mention this now: did someone tip you over the edge? Be safe.
When I first opened this thread I was worried it seemed like a suicide note! Please try to combine your first two posts, so that nobody makes that mistake (or I could just be more of a raging moron than I first thought! %)) :-/
