An Odd Email I Received - Is A Lawyer Recommended?

Late last night, I received a very odd email from a person who claimed they were a competitor, but not directly as they were not smart enough to leave their domain following this email:

(1 sentence comment about internal marketing at my firm - articles and SEO, etc.)....'To bad you are working form your apartment on the Kitchen Table. Google will catch on very soon! Regards, The Competition'

* Notice his use of 'To' he, he

The only thing I don't like is the apartment and the Google catching us. There is nothing to catch us about. Our office in New York is right on Google local and it's 4 of us full time. Even though my wife works from LA every now and then and I'm back and forth from Chicago, Houston and DC to here in NY. Now, that's what concerns me as it seems like this person is making some sort of threat. Can anyone decipher what to make of a threat like this? He has a credible (somewhat) website, but his email is just joe@domain. He is not direct competition.

Should I have my attorney contact him to scare him a little?

If you need more information to help me out, I'm more than happy to provide it.
