Kid: Dad, how did I come to this world?
Dad: I will tell you about that when you are older, son.
Kid: Why not now?
Dad: Alright, listen carefully, okay. Your Mom and Dad met each other in an internet café. In the bathroom of that café, dad connected to mom. Mom at that time made some downloads from dad’s memory stick. When dad finished uploading we discovered we didn’t use any firewall. Since it was too late to cancel or delete, nine months later we ended up with a virus.
