Keep silence for the most part, and speak only when you must, and then briefly.

What hurts this person is not the occurrence itself, for another person might not feel oppressed by this situation at all.

All human beings seek the happy life, but many confuse the means - for example, wealth and status - with that life itself. This misguided focus on the means to a good life makes people get further from the happy life. The really worthwhile things are the virtuous activities that make up the happy life, not the external means that may seem to produce it.
