The answer to this question depends on several factors, including:
- The specific theatre: Some theatres have strict policies against public displays of affection, while others are more lenient.
- The type of performance: A romantic comedy might be more accepting of kissing than a serious drama.
- The audience: If the audience is composed of families with young children, kissing might be considered inappropriate.
It's always best to check the theatre's website or contact them directly to inquire about their policy on kissing.
Generally, it is considered polite and respectful to avoid excessive displays of affection during a performance, as it can be distracting to other audience members.
