Remember that most mail is opened (and sometimes shelled) by machines not humans due to the sheer volume they receive and are stacked in bins to go to the correct department so unattached items can become lost. That is why you must always put your name & SS# on the top of all pages sent to the taxing authorities in case they get jumbled in with other returns (like if a bin is dropped). When things are handled in bulk dodo can happen.
