Were you ever surprised by the spell results?
Have you ever done some ritual/spell not expecting much result and were surprised? Or perhaps the other way, put in a lot of effort in and not much happened?
I myself am not a witch but I did a freezer spell on my very gossipy colleague after putting up with her nonsence for 5 years. I saw it on social media and really wasn't expecting much at all. Well... she fell down and hurt her arm or shoulder, was off work for a while and never bothered me again, I think I spoke to her twice in half a year. It would be a rather strong coincidence I'd say!!
