It clearly wasn’t going to attack — most likely, it got inside by accident, maybe with the flowers or while the dress was being prepared for the ceremony. The bride screamed and jerked back, but I managed to hold her so that she wouldn’t fall. The guests noticed the commotion, and several people ran closer.
At that moment, the snake, as if realizing that it had been noticed, quickly crawled out and, wriggling along the floor, moved straight to the door of the hall. The music died down, the laughter stopped, everyone watched with surprise and fear as the little guest “left” the wedding. 
Luckily, there was a person among those present who understood snakes.
He calmed everyone down and explained that it was a harmless, small snake that had accidentally ended up there and posed no threat. But this didn’t make it any easier for the bride — she spent another hour coming to her senses, trembling and refusing to continue the celebration. In the end, she decided to change: she took off her wedding dress and put on comfortable trousers.
From that day on, my wife developed a new habit: checking every corner and always being wary of long skirts.
