Download & upload

A Kid asks: 'Daddy? How did I come into this world? The Daddy Answered: 'Well, my child, some day I'll have to tell you any way, The Kid asked again: 'So why not today?' The Dad Respond: Please, listen carefully: 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. That application had no 'Undo' and it was too late to 'cancel' or 'delete', nine months later we ended up with a virus.'!!!!
