When is it appropriate to ask why someone does not drink?

It is appropriate to ask why someone does not drink in a respectful and considerate manner, ensuring that the context is suitable and the person feels comfortable. Here are some guidelines:

1. Context and Relationship: Ensure you have a close or trusting relationship with the person. It's more appropriate to ask personal questions if you know the person well.

2. Setting: Choose a private or semi-private setting where the person won't feel pressured or judged by others.

3. Timing: Avoid asking during social events where alcohol is present, as it might make the person feel singled out or uncomfortable.

4. Respect and Sensitivity: Approach the topic with genuine curiosity and respect. Be prepared to accept their answer without pressing for more details if they seem reluctant to share.

5. Non-Judgmental Attitude: Make sure your question doesn't come across as judgmental or implying that not drinking is unusual.

6. Accepting Their Response: Be ready to accept any response they give, whether it's a detailed explanation or a simple preference.

By considering these factors, you can ensure that your inquiry is appropriate and respectful.
