It's your first day on a new job, and you have no idea what to expect. You sit down at your desk, and the computer screen looks like this:
"This is going to be awesome! Let's get some real work done."
*goes bug-eyed* ... "I think it's broken."
The latest fruity gadget was just announced at WWDC:
"That looks nifty. When can I start using it?"
"Great- another way that tens of thousands of people can have personal info stolen."
A [senior] relative offers to give you this laptop from the basement:
"Wow that's awesome! You're serious- I can have it? I wonder if I can put OS/2 on it..."
"Yeah, um... no thanks, I'm good."
You suggest that you and your buddy watch a movie:
"Sure! I saw this great preview on Netflix for one..."
"Okay, let me fire up XBMC and you can browse the collection. If there's nothing in there you like we can always torrent something."
The summary: geeks are special people, with special needs. If you decide to befriend or fall in love with one, you had better a) be one yourself, or b) mentally prepare for the incessant stream of odd behavior. Don't ever assume that anything will be normal.
