One day I was just surfing the channels as I was not finding any thing intresting while surfing the channels I was stuck on sony pal where there was one serial coming which I use to see but I was wondering its the same serial which I use to watch but that show was airing with different but same story and characters I was really confused what is going on then after gettingbreally confused I surf on net to get some information of the channel then I come to know they telecast old serials with new name of a serial then I was wondering what would be the reason behind showing old serials one again at some point its nice as these serial refreshes our memory and after certain point its senseless just move onn
