I'm a beginner to Chinese so maybe I'm misled, but I find it quite silly that all books and tutorials describe the third tone as "falling-rising". This is something that left me scratching my head at the beginning of my learning because the descriptions in courses just didn't match what I was hearing. From what I hear, it seems to just be a short low tone the majority of the time, as you describe in 我家. Then it becomes a second tone before a third tone, as books say. But I hardly ever hear it as a falling-rising tone. Practically only when it's pronounced in isolation (e.g. when one is counting). So I wonder why the least frequent case is presented as the rule and the most frequent case is often not presented at all... maybe tradition from old pronunciations of Chinese?
