I have a guy dilemma?

Okay, I like this guy. So, I was joking with his younger brother (my age) that I was going to try a love spell that I found on the Internet on him, and I offered $30 for his hair. Stupid, I know, but I just wanted to see how far his younger brother would go for $30. Anyway, he found out, and I gave him a note that I thought explained it. Now he's ignoring me!!! What the heck do I do?
