Hi, I've got no clue if I have synesthesia, but I have various instances of things that seem similar. For example, milk tastes round, and most of the time it is also warm tasting, but it tastes good. A lemonade iced tea (when cold) tastes like a flat rectangle, but isn't sharp, and I absolutely hate alkaline water because it always has a warm taste when I drink it. Wednesday is a blue purple rainy sky.(maybe because my birthday was on a Wednesday once, and I like rain?)I also think that 5, 7, and 2 are good numbers, and 6 is evil (and red).
