I just like men who wear sandals barefoot in summer, because my feet are slim and look better than those of some women. I didn't know that before. I once traveled to Heidelberg, Germany, and got wet on the Rhine River, so I took off my socks. Walking in the university town, I found that many girls were staring at my feet in surprise, and some were still giggling. I heard wonderful, precious and other praise words. I found my feet tender and white when I looked at them myself. At that time, my face turned red and I felt very shy, but I was very happy. So I like to wear sandals barefoot in summer and buy a lot of neutral sandals. The next summer, when I was wearing goose yellow sandals in the London underground and all the women in the carriage stared at me in surprise, my narcissism was satisfied. As for whether the university can wear sandals, I think there should be no restrictions except going to physical education class.
