I'm scared? Read Details?

[M.C.]

Today our home internet bill arrived in the mail and on the bill it said we went over our internet limit and they had charged us $2.50 per GB. it shows how much gb we used and what they charged in total. It was a little high than what my dad usuallly pays. He complains that all the years hes been living here he never had such a problem. he announces that hes gonna call them tomorrow and find out whats going on and what made it go so high hes not sure if its becasue i have a laptop in which i do school research on. but now im scared of that call casue i had lot watched a lot of porn videos and have been trying to stop for a while now. i would do it 1 or twice a day. i would watch them on my ipod touch. are they gonna tell them that the majority of the increase was pronograpgy? are they gonna pull up thier record of all the websites visited and tell what really make it go up?? im really scared about this and if my dad finding out ill be in big trouble. the last time i did it when i was 8 but i stopped since then until now. what should i do. should i come clean before he goes and possibly figures out as hes most liekly gonna call rogers while im in school and the thought of him finding out and waiting until i get home is nerve wracking. What should i do?? and is he gonna find out??
