Using abstract nouns, adjectives, adverbs, et al.

[Jezie]

Ok ok...  This may get me into trouble...  Yet...  I am stuck.  Abstract nouns, easy enough...  But why ponder on abstract nouns and not catch the "they're
use can usually be attributed to a fit of sloth. ..." maybe it is because I break contractions up when I read and do not use them when I write.  But this line bugs me...  I do not know who Mary Oliver is...  But why was "they're" used and not "their"?  Again,  not meaning to be rude or anything,  just curious on basic grammar...  And what I am missing here...  

Oops, it wasn't Mary Oliver (who is a famous Pulitzer Prize winning poet that, if unslothfully Googled,
will appear in every result from 1 to 1000 in under a second); it was me not checking my Dragon Dictate
text carefully enough. (My sloth prefers dictating texts from books rather than typing them.) The Dragon
sometimes confuses "there", "they're", and "their"; and since my spell-checker thinks they're there
for their intended purposes (it doesn't, unfortunately, have a context checker), it leaves it to inattentive,
slothful me to proof-read the damn thing.

I have corrected my error.  Anyone reading this thread from now 'til the end of time will be confused
if they're too slothful to read the whole thing.


Billy! You still haven't answered my burning question:
Which term is more prevalent in good old Britain: "bullshite" or "bullshit" ?
(Inquiring minds need to know.)

Ah... Was wondering... Thank you
