(Marvin Schiller, "The Sheep's in the Meadow,"...)

It was late , we were playing kissing games , and Jessica and I called_on to kiss in_front_of the others .

All about me there was a hectic interplay of meetings taking_place , like abrupt , jerky scenes in old silent_movies , joyous greetings and beginnings , huggings and kissings , enthusiastic forays into the festive night .
