Three things, IMO.
Knowledge, experience and honesty. Anything else is a bonus.
The first time I learned to pack, my jumpmaster threw me to the senior rigger. He made sure I understood each step before moving on to the next. Throughout the whole time, I was treated with respect and my questions were answered before we continued packing.
He might not be a good person, but he knows what he's doing, he's not arrogant about it and he's not selfish with his knowledge.
My two cents. Why don't you just go to the police station in a red clown suit and let everybody know what we're doing here?
I have a phobia for moobs. Thanks, youknowwhoyouare.
