Here, I helped middle and high school aged people build small single-lined maneuverable kites (aka fighter kites) and we talked about how easy it is to untangle kites should their lines cross. Instead of moving away from each other, they should walk towards one another thus causing the lines’ knots to slide down closer to the kite fliers. Once the knots get to the fliers, they can determine how to untangle themselves easily.
Likewise, I said, if two people are in a fuss, instead of walking away, they should walk towards one another so that disagreements can be talked about and “knots” can be “untangled.”
We have no "Brick and Mortar" store yet, but call or email me if you're interested in buying a kite and we can set something up.
