    A fun next lesson is the benefit of apparent wind. In addition to the wind relative to the water, you have added wind generated by the movement of the boat. Since the lift generated is related to the speed of the wind relative to the boat, the faster the boat goes, the more lift you get. As a result, it is possible to actually sail faster than the wind speed of the wind relative to the water.

    I’m pretty sure I did a bad job explaining that. Google can explain it better for sure.

    I try to never use “the finger” when another driver is being an ass. In that case I always just give them a thumbs down and a sad face.

    I save the middle finger for people who are being “nice”, especially when it is making things dangerous. I find it is the quickest way get them to just go.

    I try to be coniderate while driving. Being predictable is safe. Deviating from the rules is dangerous. I think being safe more considerate than being “nice”.
