Dude, the workplace is not the same.
Between all the job losses, people are so uptight these days. Women can secretly write you up and then if you hit on her she can get you fired. My boss told me he had to fire someone because of that. I dated a girl from work a few years ago and another guy got fired for punching me over it (and he went and reported me but then they fired him instead).
And never email girls from work. They will forward it to their supervisor and make a big deal about it, especially married, unattractive girls, or the catty receptionist who knows she makes the least in the company and is seething.
KISS OF DEATH: Because so much information is now available online, if you ever forward a link to someone at work to support your claim, especially a scientific link in a scientific job, and ESPECIALLY one that YOU wrote as a professional in that area, it's practically grounds for dismissal these days. People have dynamically become more ignorant to maintain their pre-internet level of stupidity. Goddamn anyone who was ever offended by a hyperlink, a quote, or an email rant.
Just smile and politely answer questions and walk away. Tell them you have a girlfriend.
