Skype confusion - Weekend!

Being very anxious to reduce my landline ISD bills, i borrowed credit card from my friend and got credit points in skype for 10$ and called up to inform my bills will be less this month. Was horrified to see 0.36$ in 25 minutes.Oh man! Almost Rs.500 for 25 minutes. Then explored to get more information regarding it. Found that calling mobile was 17 times costlier than landline. Then found that if i called landline i could have spoken for 8 hours for the same Rs.500. Its ok! A lesson learnt but quiet a costly one.Decided to call up landline only on weekdays. Lets see this month bills.Weekend was ok. Friend U's parents and in-laws had come. Nice people. Had good home made food. Raagi dosa and fantastic sambhar.Yummy. Then started for morning walk today at 6.15PM. My watch was ten minutes slow and the cab came at the right time when i just stepped out of house. Then RUN..RUN..RUN to catch the cab. MY god. Should keep the time on my watch and the cab's clock in sync to avoid last minute rush!
