Boys are too shy to play, so let go and sing loudly. Who can play musical instruments beautifully when they are born? In fact, I can think of your roommate to show that you are still very kind, but if you want to consider the occasion, even if you play well, everyone will be noisy when they rest. Your school club will have guitar lessons on weekends. Then, take the time to practice well, and ask if you don't understand. Don't think that the teacher thinks you have many problems. You can take the piano to exercise from Monday to Friday night. There were not many people practicing on the playground at that time. If you practice well, think about it: at night, you and your girlfriend are sitting on the grass in the playground, the piano is melodious and the moonlight is bright. How romantic it should be (in fact, these are all things I have experienced. I've been practicing piano for five years, and I'm beginning to applaud like you, so you must let go and don't feel embarrassed about practicing piano. I think I need a little interest and some perseverance. Finally, I wish you success in your study)
