How do I explain my choice easily to my mom?

I understand where you are coming from. I grew up in a strict Christian family. I always felt there was more to it. I was in 6th grade at the time when I first discovered Wicca, I was drawn to it instantly. I felt like it was right it was where I belonged. I kept it hidden as well as I could but not even in to 3 weeks of taking the reed mom found out. She had been doing laundry and putting things away when she found my Book Of Shadows. She ripped and burned it before my eyes. She told me it was devil's work and I would burn for eternity if I did not pray for forgiveness. I did not let my mom dictate my life I continue to practice almost 7 years later. My mother still hates that part of me. Please take my advise it will make things so much easier. Wait till your older. I wished I had waited till I was 18 to tell my mother. I learned from my mistake. Trust your heart you will know when the time is right.
