i had woman employee say to me "silly rabit tricks are for kids" when she hasn't even seen any cool magic tricks before. she's never even heard of criss angel!!!! and she's 22!!
Oh my ! I hope someone alerted the authorities !!!!
Seriously, it's obvious she didn't want to see any magic at the time. Don't take it personally. Secondly, you saying "I'll show her some magic that will make her regret she said that". Makes you look and sound like an angry little child that got scolded. With an attitude like that, well let's just say that won't win anyone's respect. Third, don't use magic as a means to get back at someone. That doesn't make you a better magician. It makes you look like a little smart-a$$ed trixter.....nothing more.
If you want to get her on your side, you can make a joke out of her remark, and just keep it between the two of you. "Silly Rabbit! Trix are for kids"! ...."Yeah. That's what I used to think, until my cousin told me she was gettin' $100.00 a trick."
Oh well just my thoughts on the subject.
