I've cultivated the habit of saying "my condolences" really solemnly to even smallish complaints, because I am frustrated by that exact thing. It has the added benefit of often making people snort and feel slightly better.
Either people need to learn how to tell the difference between an “I’m sorry” that takes direct responsibility and an “I’m sorry” that signifies sympathy, or I’m gonna start responding to unfortunate information with a solemn nod and a “Sympies,” because I am tired of receiving a “Why? It wasn’t your fault” every time I try to vocalize compassion.
