Don’t overuse periods. In fact, don’t overuse anything on a keyboard if you want to get your point across. I work in customer service and have seen plenty of self expression overkill jobs over the years, but trying to stress a point with periods is simply annoying and ineffectual.
I’m. Talking. About. This.
Just as putting the caps lock on is akin to shouting in an email, periods look as if one is punching the reader senseless by beating the point into them. Next to not using commas as often as necessary, overusing periods is an instant clue that the rest of the communication is going to be nothing but nonstop whining.
What ever happened to the simple, “I’m having a problem, and I hope you can you help me” types of emails? We all seem to have been rewired into a bunch of bile-spleened idiots with no sense of decorum.
I, however, will not give up the fight. I answer all emails politely and calmly. Period.
