hey i use magic a lot in my sets as it can demonstrate value, if a girl asks you to show her the trick again then use this as it always get a laugh.
"sorry i'm like any typical guy . . . once i have performed once i need 10 minutes for my batteries to recharge"
when she asks you how it is done reply by saying
"i cant tell you that . . . (smile) and then say i like giving people that feeling like anything is possible and i dont want to take that away from you" then just move the conversation on.
happy hunting boys
