You're a Entrepreneur or Business Owner.
...And when you want to have fun with it, just say your the CEO & President of a major Online Pharmaceutical Operation.
Then they say wtf does that mean? You simply say... "I push pills" and at that point they are so fucking confused the questions will stop.
Them: So, what do you do for a living?
Me: I make websites.
Them: On the internet?
Me: Usually.
Them: Do you make them for companies?
Me: Mostly.
Them: Which companies?
Me: Sorry, I'm not allowed to talk about my clients.
Them: But does it pay well?
Me: No, it really doesn't. I've been at this for 8 years, and I am thinking about going back to school.
Them: Oh, that's too bad.
Me: Yeah, the internet is just a fad. I'm getting out while the getting is good.
I am own an advertising agency that specializes in lead generation and customer acquisition for companies like Netflix and Blockbuster.
(see Netflix/Blockbuster is thrown in there b/c people know them so they aren't going to be that confused and they are impressed that someone in cut off shorts and flip flops works with a reputable company - and THAT explains the fancy cars)
