Lou offered me a choice of green, red or chai tea. I opted for green. According to what I was once told, green tea has a mild flavour, as long as it is not over-infused. But the most important thing is that it has I don't know how many beneficial properties for health, among which its antioxidant effect stands out. Oxidation is a chemical reaction where an element gives up electrons, which leads to a reduction of the element itself. This is what happens, for example, with the corrosion of metals. And it seems that living beings also oxidise and that there are products such as tea that help us to avoid it (a little). I sipped it, sitting on a sofa facing a courtyard presided over by a splendid mandarin tree and surrounded by vines. I don't know if it was the tea, the silence, the good company or the presence of the mandarin tree, but I felt good, further away than ever from the corrosion of the city.
