>A truthful person is able to convey the smile that is present on their face as :-) as they are typing the emoticon.

And you, of course, are the only 'truthful' person present...

OK, so why don't YOUR emoticons represent "mirth" (def: great
merriment)? Are they false smiles? And why aren't YOUR emoticons
considered "written laughter"?

You know what they say about written laughter.
