The above exchange illustrates a problem with the Internet in general and occasionally has particular pertinence for this forum. Are we a bunch of like minded mates in a virtual pub, or are we a bunch of loosely like- minded virtual strangers all invited to an imaginary cocktail party?
If the former, its perfectly acceptable to adopt EMartnJ''s 'what the fuck were you thinking?' approach.
If the latter, its more appropriate to adopt Southernstyle's 'excuse me my good man, might I just steer you in a slightly different direction' approach.
The problem arises because the entire world can't make its mind up what it wants the Internet to be.
It's not that simple. Doyleclark is fairly new around here. If someone were new to a pub, I hope EMartNJ's comment would not be the first thing out of your mouth when talking to them. It takes time to build to a point where you know someone is just joking. Unless they have history, I'd say it was too early. Secondly, I tend to surround myself with friendly people. Even if they didn't like something I was wearing, they would only say so politely. It's nice to be nice.
