THIS IS NOT GOOD EMAIL ETIQUETTE

I JUST RECEIVED AN EMAIL FROM A GUY WHO HAD NOTHING MEAN OR RUDE TO SAY BUT HE TYPED IN ALL CAPS. IT WAS ACTUALLY A LOVELY EMAIL EXCEPT FOR THE FACT THAT WHEN THE VOICE IN MY HEAD READ IT TO ME, IT WAS SCREAMING. DO PEOPLE STILL NOT KNOW THAT THIS IS BAD MANNERS? I THINK THAT THIS IS A GUY THING. I HAVE NEVER HAD A GIRL SEND A NOTE OR EMAIL LIKE THIS. A WORD OR TWO FOR EMPHASIS, BUT THE WHOLE THING? I HAD TO DIG THIS CARTOON UP JUST FOR THIS EMAIL TODAY.
