Alone in a strange city, there is no place to live at night. Can he stay with friends of the opposite sex for two or three days?

For this problem, I suggest you make a decision according to your own wishes and security considerations. Here are some factors that may need to be considered:

Security: Staying in a strange city may have some security risks, such as being stolen and cheated. If you decide to be with friends of the opposite sex, you need to ensure your personal safety.

Relationship: If you have a very good relationship and believe that the other party will not cross the line in behavior, then * * * can live together. But if you are not intimate enough or you have doubts about his feelings, it is recommended to find other ways to accommodate.

Social morality: * * Sleeping in a bed does not necessarily violate social morality, but there may be different views and attitudes in different cultural and social backgrounds. If you care about other people's opinions and comments, consider this factor.

Legality: We should also pay attention to the relevant local laws and regulations, whether to allow single men and single women to live together, otherwise it may involve illegal issues.

In short, if you decide to be with friends of the opposite sex, it is recommended to discuss with each other in advance, abide by basic etiquette and ethics, and ensure your personal safety and legitimacy. At the same time, we can also consider looking for other accommodation methods, such as hotels and youth hostels, to reduce risks and avoid embarrassment.
