i type fast, but that doesnt mean i spell wrong (unless im using a keyboard with sticky keys), i just dont capitalize when in a rush.
i know how to spell im 20 not some dum kid
and that saying doesnt applie cause they ant fooling me they just dont know ****
secondly, its dumb, not dum and i doubt thats a typo.
thirdly, you can't be too smart urself if you dont see how the saying applies. It applies b/c u said they've done it to you more than once. That means you knew they didnt know their stuff, but you listened to them anyways.
