Why do many people say that the university is a mess, many hotels outside are full every night, and I haven't even touched a woman's hand for four years?

Yes, the university is in a mess now, but there are also some unclean things. But you haven't touched a woman's hand in four years. You are excellent and a very traditional person. You don't want to give the best moment of your life to someone you don't love. In short, you are a moral person. May you have a better future!
