What is the experience of not being able to ride a bike in college?

Growing up, I put up with people hearing "Can't you ride a bike?" After that, I gave a really great look. The only means of transportation to go out is the bus. Sometimes you have to find a "driver" to go out with friends. I like walking. When I was at school, I saw an article similar to 100 Skills that Men Must Master. I opened the first one: "I can ride a bike" and closed it silently. At school, my friend in the upper bunk rented a tandem bike (I was fine in the back), and we rode it to another university in the same city to attend a lecture. He left early on the way. When you come back, invite a beautiful female classmate to experience a tandem bike and say to her, you come to the front and pedal. One summer, my ex and I went back to our hometown to visit her grandmother. When I went, she rode an electric car to see me off. When I left, my grandmother and cousin came out to see me off. My ex was sitting in the back seat of the car and gestured to me with her eyes. Tell me frankly that you ride a bike, but I can't. I have tried to study it several times and bought a second-hand car myself, but I failed every time. I once wanted a big stroller with auxiliary wheels. I declared that I was "not simple in mind and underdeveloped in limbs" and explained what "cerebellar underdevelopment" was to my family who urged me to learn to ride a bicycle.
