Your nontechnical co-workers will use you as personal tech support for their home PCs
Your co-workers (in addition to your friends, family, and neighbors) will view you as their personal tech support department for their home PCs and home networks. They will e-mail you, call you, and/or stop by your office to talk about how to deal with the virus that took over their home PC or the wireless router that stopped working after the last power outage and to ask you how to put their photos and videos on the Web so their grandparents can view them.
Some of them might even ask you if they can bring their home PC to the office for you to fix it. The polite ones will offer to pay you, but some of them will just hope or expect you can help them for free. Helping these folks can be very rewarding, but you have to be careful about where to draw the line and know when to decline.
