This sentence expressed that marriage might make love dull or even grave, but love in the grave seemed to be more reliable than love in the street. However, this was only a metaphor and there was no definite answer. Which one was better, a love buried in the ground or a love that died on the streets, depended on one's personal values and outlook on life. Some people believe that stable marriages and long-term relationships can provide security and make people's relationships stronger. On the other hand, some people believe that love should be a passionate and romantic experience rather than a stable marriage. Therefore, there was no simple answer to this question. It had to be decided according to the specific situation and personal preferences.
