LEARNING TO PASS AS UPPER MIDDLE CLASS.

It transpires that I mis-stated the absence of business guru John T. Molloy, who made a living selling advice to young people, not to the manor born, on how to present themselves as though they were.  (It helps to stay away from off-the-books tattooists.)

He's still at work, to wit:

I suggest you approach the executives you accompany to these meetings and ask them if they think you would be more effective if you wore a conservative shirt and a blue blazer when talking to the executives of client companies.  Even if they say that they would rather you look like a techie, it will show you think in terms of image and make it more likely that they will move you into a position that requires that you’re dressed better.

However, your image is not your main problem. I edit most letters that are sent to me because I want them to fit into this blog and I want them to ask questions succinctly and ask questions that are of interest to the readers of this blog.  I also clean them up just a bit when needed. I do not wish to hurt your feelings but you letter indicated that you are not familiar with standard American English.  If it was  read by someone who had no background teaching English they might think that you were ignorant and semi-literate and obviously that would dramatically affect your chances of moving into the executive ranks.

Yes, passing is hard work, but not knowing how to pass and scraping by on the margins is harder.
