I've been having some problems with a friend of mine who has justed started out in magic. Whenever I do an effect he goes and looks up how to do it. This is not what annoys me. What annoys me is that the day after he learns an effect he goes and performs it. I'm aware this is normal for a self working or very easy trick but thats not the case. Then after he learns it the next day he performs it in school. So I've been practicing my snap change for about two months and its very smooth and clean. The day after he learns it he comes in to class does a sucky job of it and everyone then knows how its done. I dont know what to say to him. any ideas? I dont want to be too harsh because I already gave him like an epic lecture on revealing tricks which he was also doing.
