Addiction can be a brutal and ugly thing. We doubt that some teenage at a party, when offered an illicit substance for the first time, says, "Why yes, I'd love to do degrading things in back alleys someday. Let's see where this leads us."
No, the lure is pleasure, comfort and a bit of a thrill. It's only later, when the cravings won't stop that even the most impossible idea seems not only plausible but perfectly sensible.
Most of us started windsurfing on a pleasant, warm and gentle day. A caressing breeze filled the sail and momentary lapses of balance only meant a swim in refreshing if not warm water. It was all so fun. So innocent.
Soon equipment was bought. And then more equipment. You maybe had to bargain with the spouse to justify a new (to you, at least) piece of equipment. Maybe you didn't reveal how much that sail cost after shipping and taxes. But, you were really beginning to enjoy the sport and a mast here and fin there didn't seem like a big deal.
