I always follow my brother, although very different we are. You can see him, but not me. You can hear me, but not him. What am I?

Common Wrong Answers

Shadow

A shadow does follow its source (the object casting it), but it does not fit the criteria of being able to be heard. Shadows are visual and do not produce sound.

Echo

An echo follows sound waves and can be heard, but it does not have a 'brother' that is visible. The riddle specifically mentions being able to see the brother, which an echo does not fulfill.

Rain

Rain often accompanies thunderstorms, but it does not follow lightning in a way that fits the riddle. Additionally, rain cannot be heard in the way that thunder can.
