Early spring has arrived. The air temperature shifted from foot to foot, like an unlucky schoolboy at the blackboard who forgot to learn the next lesson assigned to him by a hated teacher: minus - plus, minus - plus. The snow melting on the roofs of buildings, as if on cue, either slid down or stopped, waiting for the next command: plus means crawl; minus - stop. It was Sunday evening, a weekend evening. So reverently important for any student, when you still wanted to walk and joke around. But the approach of the school week slowed down desires and rearranged thoughts in a responsible way. Friends woke up from the morning feast and came to their senses.
