WESTWOOD — The UCLA community was relieved to discover yesterday afternoon that the students concealed by a large picnic blanket were just trying to watch a video without glare, or maybe got cold. “Boy, that is a lot of shifting around,” said one campus goer, who hoped the pair could find a comfortable seating arrangement soon. “Oh, now that dog won’t leave them alone. It wants the blanket! Off leash in a public area, for shame!” At press time, the couple was sharing a cigarette.
