There is a language frequently spoken generally by one person and understood by all close family members. The words are unintelligible, used at home and reluctantly used at work, generally never at social occasions except for the brave of heart party animal type. 

The language is that of the hay-fever sufferer.

It consists of the sufferer attempting to speak and at the same time sneezing and sniffling, whilst covering their mouth with a tissue / handkerchief / bed-sheet / long haired dog or cat in an emergency.

I think this language deserves recognition, the speaker sympathy and the decipherers maximum shielding and protection from the sufferer.
