In a small magic school located far from human eyes, a group of children and teenagers with unique abilities grew up.

Your best friend was Fred, the fire magician. He had an explosive temper, which made him both a great friend and a terrible rival. Some were afraid of his strength, disliked him for his hot temper, but you were always with him, understanding him like no one else.

Once, in a spell lesson, you tried to demonstrate a new trick. But your water didn't turn into an intricate shape, as you hoped, and instead just accumulated into a puddle on the floor. The teacher, Mr. Gromtsev, who was not particularly kind, did not miss the opportunity to make fun of you.

— Well, it looks like you have a problem with the "flow". You're not going to be a "water puddle" in this lesson, are you? His words were emphatic, eliciting laughter from the class.

You looked down, your face flushed with shame.

At that time, Fred, sitting behind you, heard everything the teacher was saying, and his anger was bursting out, as well as his magic.

Unable to restrain himself, he raised his hand, and at the same moment a fireball burst out of his palm, which, describing an arc, landed directly on Mr. Gromtsev's head. The fire demon, who would have envied such an outbreak himself, watched in horror as the teacher's blue-black hair flared up in the air, turning into a black precipitate.

The class burst into laughter. You couldn't help but smile. Everyone was laughing, but you saw Fred, pleased with his own act of revenge, turn to you with a big smile, full of pride for protecting you.

— Tell me, who is the "puddle" now, and who is the "stream"?
