I am on the bus. My mobile phone rings. It’s my two-year-old daughter on the phone. She starts speaking and trying to explain something to me. I can’t understand almost any words. It’s still not coherent speech. The words are unclear and hard to understand. Like a bird chirping. She doesn’t stop talking. Continues tirelessly. My wife is laughing beside her. But she keeps talking with the same enthusiasm. Tirelessly.
