Colds stink. Have some tea and feel better soon. :]

The "mail goggles" thing is funny. Oddly, as much as I hate math, this would not deter me from sending angry e-mails late at night because I become focused. I would simply pull up my computer's calculator and give it the answers it wanted, or I would retract the setting. A language problem would slow me down and give me time to reconsider, though. However, as you've pointed out, such a thing might be too much fun and friends would grow tired of spam-like e-mails just to say hi! Is it a bad thing to enjoy diagramming sentences?
