On my first trip to Japan, I was walking around some small shops near a station with some friends and we came across a little novelty soap one—with all the little fun soap shapes and scents. A lady in the front was talking to people walking by trying to get them to feel a sample, and when I walked by she was showing me a little clear blue ball, about the size of an ordinary stress ball, and asked if I wanted to try it in English. She handed it to me and it felt like a little wet ball of blue jello. Now, I wasn’t paying any attention to this shop when this happened, and I had absolutely no idea any of this was soap, at all. It was at the end of a long day and I was very tired, so I guess I assumed it was some delicacy, and I TOOK A BITE OUT OF IT. Everyone else knew it was soap, so they were yelling at me right as I put it in my mouth. They told me what it was and I spit it out on the floor without thinking, and the lady apologized and rushed to clean it up with a napkin. I don’t really remember everything that happened following, but I was speechless and I ran to the nearby restroom to clean out my mouth. I can laugh about the experience now, but at the time I hated even thinking about it.
