I know doctors go through this all the time. You're at a party and someone wants you to evaluate a mole on their arm.
The technology equivalent is a misbehaving camera or mobile phone. Actually, I take that back. I'd rather look at 10 malfunctioning cameras rather than one questionable mole.
The bottom line is, every family has a tech support guy. And he's busiest during the holiday season. When the wrapping paper comes off, the nerd hat goes on.
To tell you the truth, I don't mind this role. For years, my family had no idea how to describe what I do. They still don't really. But they can say, "Derrick is really good at tech. And he knows how to set up printers too!"
Like I said earlier... it beats the heck out of looking at someone's birthmark.
