You'll probably want an 'h' at the end of throug. ;O)
But at least when this is pointed out to you, you won't issue a blanket, and blank, denial of the correct spelling.
:^) - Sometimes my brain knows the spelling but my fingers are on automatic pilot... but in this instance, the batteries in my Apple bluetooth keyboard are dying... and tossing extra keypresses including the delete keys. It can be frustrating trying to type "Petronski" and getting "PPPPPPPPPeeeeeetronski." I then hit the backspace key and it does the same thing... and sometimes I don't catch the extra deleted characters. I guess I should go the to store and get a set of AA batteries.
You know, proofreading one's own work is extremely difficult. My brain fills in what I meant to type.
