At work, we have an outside party who consistently sends us email messages like this:

That Works For me On This End. Would You Be Able To Send Direct To The Customer???

That Would be Even Better Than Sending To Me.

Thanks,

This drives me crazy in ways I can't begin to explain. Why?! Why start each word with a capital letter? Even if the person was originally from Germany, only their nouns are capitalized. Try typing a sentence or two like that--it's awkward and time consuming. This person either never took any sort of English class, ever, or thinks this looks more official for some reason. 

End of rant.
