I am just curious if I am the only one who cringes when reading other's works and discovering errors in the usage of:
to, too, two
their, there, they're
a, an
and other common word usage errors?
Am I too uptight about this. Do people want these errors pointed out to them? I know I sometimes make these same mistakes (and others) out of haste and/or sloppiness, but I get the feeling some make these mistakes out of (sorry, can't come up with a better word) ignorance. Is this just me? Just wondering. Don't mean to be overly critical. Thanks for your responses.
