How to convince my paretns for a facebook?

[Blue Egyptian]

i just went behind thier back. and used facebook at my friend's houses. then i had family and friends tell my parents how cool and fun facebook is. then i found out that my mom was convinced and she got a facebook. and then someone spilled the beans that i had one. but she was cool with it because she now realized how fun it was. my dad also liked it because i can give his business free advertising on facebook. he still wont get one. but through my account i have done all sorts of advertising for his business.
