When is it stalking?

I am an older person who does not understand the persistent quality of the electronic correspondence I receive. I recently turned down an opportunity to advertise my business in our local newspaper. (Couldn’t afford it.) Afterward, the sales rep sent me two angry e-mails, and phoned me to ask me to explain my decision.

Were this 1975, I would have stir-fried this little dame for dinner by now. But because it is 2010 and because she grew up on the anonymous, consequence-free Internet, I’m cutting her a lot of slack.

Am I right? It this a generational thing that I should continue to silently wait out, or do I have a stalker?
