Qinghe declined, "The old master and my two uncles must have matters to discuss, right? We had a late breakfast and are still not hungry. It's a good time to take a walk in the garden to help with digestion, and then we can eat a bit more later." As if she would be so foolish as to get involved in whatever issue was at hand—she couldn't distance herself fast enough. She'd keep out of Gu Family affairs when she could. The less trouble that found her, the better, given her limited curiosity and desire to know more.
With such appropriately measured and courteous words, had there been outsiders present, someone would've surely praised her for being well-mannered and tactful. However, everyone in the room knew Qinghe's character—she was well aware that something was amiss and wanted to steer clear of it.
