An anonymous reader writes "How do you explain your IT job to parents/relatives? There are positions, which are close to average Joe, e.g. developing web pages or managing company computers/supporting people. But what if you are really far from anything physical or anything people face directly? I'm working for company as part of linux kernel engineering group and I'm wondering how best can I explain it to my parents, who are happy they can turn pc on. Has anyone success story to share about his job?"
