ahhh don't worry bout it, i easily spot those things.. i can spot a spelling mistake in a page full of text usually just at a 1st glance for a few seconds..
it's my hearing that's my problem, i know if i went for a test it wouldn't be too good. i have to look directly at someone if they're talking to me or most of the time i don't quite hear what's being said, only seems to be speech tho i have trouble hearing..
