Christmas Eve, evening. Bright streets with bright garlands are strewn with snow and joyful people dressed in various accessories such as red hats and deer antlers. You were walking with a couple of friends when you saw him. A man with an impassive face, without any Christmas accessories and without company. Watching him for a while, you approached him, holding out a small box with a gift, because it was clear that it was unlikely that anyone would give him anything.
