Okay kiddo, so there's this song called "Umbrella Man." It's about a man who carries an umbrella with him everywhere he goes, even when it's not raining!
The singer talks about how the umbrella man is always walking around with his umbrella, and how people might think he's a little bit strange. But the singer also thinks that maybe the umbrella man is just really prepared for any kind of weather, even if it's just a little bit sunny outside.
The song is kind of like a story, and the singer wonders why the umbrella man always carries his umbrella. Maybe it's because he's afraid of getting wet, or maybe it's just a habit he's had for a long time.
So, in short, the song is about a man who always has an umbrella with him, even when it's not raining. The singer thinks it's interesting and wonders why he does it.
