How Do People React When They Find Out You Work Online?

When my relatives knew i was working online they were shocked because they were thinking that i am doing such cyber sex to gain money well in fact Im not a bitch like that, and so when I said like I am doing affiliate marketing etc, they still don't trust me and keeps on doubting.. I just leave them off and continue to work, after a month I bought my new iPad2 and then that moment they began to believe when I had my first $500 income. Skeptical though we have to face it.

Just say it's too hard to replicate, so just keep your job.
