I figured that my mom will find out eventually so i figured it was best to tell her and, to be honest I was a nervous wreck when i told my mom (I refer to her as Monny {dont ask}) Monny and I are like sisters, and i was sort of afriad i'd loose that. So at the time i told her i was near panicing when i told her. Well, she took it very well. She said she didn't know very much and wanted to learn more. And a few weeks later was helping me look through books on Wicca at the book store.  To be honest I'm lucky to have suck an open minded mom.  But for those of you that aren't so lucky I've added some links to help.
