i love magic that is just going up and doing something without asking them if they want to see something
I take it that you love being punched in the face then?
The "attack" form of Magical "Performance" has no sense of class let alone anything that resembled RESPECT. . . whatever happened to the idea of treating people the way you would like to be treated?
If some stranger runs up to me and invades my personal space without invitation I will respond in a manner that equates to self-defense i.e. thumping them with my cane or running over their toes with my wheelchair (with me in it we're talking 500 lbs across your instep). In certain parts of this country the reaction could very well be a gun muzzle in your face or a knife in your gut.
So, ignoring the stupidity behind such tactics and the obvious lack of grace such a person seems to possess, why do so many of today's young people think it perfectly fine to jump out of the bushes and shove a deck of cards in someone's face?
If you want to do Street Magic, then learn to build a tip and do a solid job with the gab so that you have a decent crowd that will pay you based on what they think your deserve -- EARN THE KUDOS vs encouraging applause as a way to make you leave.
There's a guy on another forum that thinks "doing a show" is going out to the mall or park and doing a couple of tricks -- far from it! Such things are "bits" or "teasers" as we used to refer to them; the things that get people through the front door of the side show where you pump them for the cash. That's (metaphorically) what sidewalk magic is about, not molesting people that just happen to cross your path.
I'm confident at least one of your parents have said this to you but as a grumpy old guy thats' been around this stuff far too long I'll say it just so you might hear it this time, 'GROW UP!" If you love magic then respect it as well as your audience and your self by doing it right, with dignity and style; do it in a way that offers the prospect their freedom to say NO and walk away without being harassed. Learn to give the public something they want to experience so you and EARN their trust, their money and their word-of-mouth PR.
Think about it!
