Spell Check?!

Does it eerk anyone else that people mess up simple spelling? I can't tell you how many times I see (what I think of as) simple words being spelled incorrectly by numerous people. Maybe even adding to that the misuse use words that have many different spellings.

About = aboute
Thief = theif
There = their or they're
Boobies = bewbies or bubbies
Items = Idems
Tomorrow = Tomarow
Which = witch
What = wat
School = skool
Awful = aweful
Misspelled = mispelled
Argument = arguement
Believe = beleive
Committed = comitted
Dumb = dum
Damn = dam or damm
Exceed = excede
Grateful = greatful
Jewelry = jewellery or jewelery
Piece = peace
License = lisence
Midieval = Mideval
Rhyme = rime or ryme
Vacuum = vaccum or vaccumm
Good = gooder

This is the short list of what bugs me. I know I'm not a highly educated person but I know how to spell general american-english words. The sad thing is that folks who come into this country learn our language and spelling better then the kids we teach in OUR school system. I have two younger cousins (18 and 17 years old) and they misspell and misuse words all the time. I feel bad for them but it seems no matter how much I try to correct them it never helps. It is very difficult to teach someone something they believe they already learned. Misspelling words online is just about the worst thing because almost EVERY computer these days has a "Spell Check" option and not using it is just lazy. If you get made fun of online for spelling or grammar errors, well... it's your own fault. I mess up too and likely have in this particular thread but at least I make an EFFORT to correct myself.

Epic fail America. Epic FAIL.
