When considering the THINK questions, Xavier might answer "yes" to the following criteria questions:
- Is it true? (If he genuinely believes she looks tired)
- Is it necessary? (If he thinks it's important to share this observation for her benefit)
However, the key questions here are whether his comment could be perceived as helpful or kind. Generally, commenting that someone looks tired could be seen as unkind or not particularly helpful, unless it's framed in a considerate way that shows care for her well-being.
