On seeing the replies, my first thought was that the original poster might have been writing ASL word order, not uncommon if that's the primary and most comfortable language -- especially since most of us relax our writing style, get more casual -- in non-work-related email (and on forums
) I think this would be related to (not caused by) the friend's deafness and means of communicating.
But, after looking at the errors quoted, that doesn't read like ASL to English to me, or English as a second language -- just your average young person's overly casual/sloppy writing to a buddy. Not really a big issue, is it? My husband is a high school teacher who runs several online groups in which his students collaborate with one another on creative writing activities, and their online conversations are pretty scary overall, grammatically-speaking. They clean up their acts, though, when emailing directly to him.
