Pretentiousness or an economical use of space?

...That is the question.

I'm speaking about the use of one letter as a substitute for a person's signature at the end of an email.

So instead of a friendly 'Claire', it becomes a stark 'C'. And it glares at me from the bottom of the hotmail window. Despite how warm or glowing the correspondence makes me feel -- when ended so abruptly me, I'm left empty and barren.

Is it pretentiousness that drives a person to opt for one letter? Are they thinking 'I'm so busy I don't have the time to tell you who I am'? Or do they think they own that letter - for example, no other names start with C? So in their world a Chantelle, a Charlotte or a Charlize doesn't exist.

Or are they grabbing onto the latest market jargon of being 'time poor, cash rich' folk? It could be that they are merely exercising this fact of being 'time poor'. It is the economical use of spelling their name with just one letter that regains some precious time. But is it really worth it if your name is Will?

Now, I'm kind of guessing that I will receive a few angry responses. Because a lot of people out there do it.

Some days it's good to be controversial.
