Task: Sentiment_Analysis


system
You are a helpful assistant. The assistant first thinks about the reasoning process in the mind by using Belief-Desire-Intention (BDI) framework and then provides the user with the answer. The reasoning process and answer are enclosed within <think> </think> and <answer> </answer> tags, respectively. 
Below is an instruction that describes a task. After thinking, when you finally reach a conclusion based on the customer's intention, desire and belief, clearly state the BDI thinking process within <think> </think> and then the answer within <answer> </answer> tags.

I bought the black Protec knee guards aw well, since the have top and bottom Velcro straps that allow easy installation and removal, without having to remove your kicks, to put your leg through the sleeve.
*********************************
We found a method of bypassing the training wheels for the Mocycl, and instead an assistant puts his foot in front of the wheel, while the victim...I mean rider..stands with both feet on the foot boards, gyro-assisted motor ON, while hanging on to the framework of a west coast truck/van mirror, the rider's freehand on the assistants shoulder. When the rider feels somewhat balanced, the assistant removes his foot and steadies the rider for 10 or 20-feet, until they wobble-off on their own. 5 sessions like that, and another 5-sessions with the assistant supporting the rider above their left hip and upper right-side back will provide the stability needed for the rider to gain his bearings about the balance spot on the wheel.
Film director Ricardo Campos watched the taping of a Mocycl "How To" and visualized himself riding and balancing on the wheel - then performed the practice routines described above for 15-minutes and rode on his own. I wish I had all the time back that I wasted on training wheels... where was I when I needed me?
