Last year before I was a wiccan, or even knew it existed my friends and I were on our computers. One of my friends Della pulled up the pentacle. At the time I thought the pentacle was just a star, because asides from Black Butler I had never heard of it. My friend Ali looks over at us and sees the symbol. He looks at us horrified and starts freaking out a little. He told us that symbol was evil. I tried to calm him down and tell him the symbol was just a star. He looked at us worriedly and tells us because of his religion he hates that symbol. (Actually don't know what religion Ali is but seeing how he reacted I think he's Christian).
Fast forward a bit and I discover Wicca. I become extremely dedicated and research as mush as possible.
Today in class I was looking "Witchy" on the inter-webs stuff and Ali snuck up behind me. I didn't notice him because I was copying thing into my book of shadows. When I did notice him I quickly shut my laptop. He looked at me all suspicious and said, "I know what you're up to." Then walked away. At first I was a little worried but I shrugged it off. Later, Ali snuck up on me AGAIN to see what I was doing. Again I shut my laptop. He looked At me and asked."Lulu, are you a witch?" I pretended I didn't hear him. "Guys, I think Lulu is a witch." He told the people sitting around me. I tried to tell him that witches do not exist (Which crushed my soul to say that) but I'm not sure he believed me. I was going to tell Ali I was a witch but I don't want to ruin our friendship. And now I'm worried he found me out what should I do? (-_-;)
