This story was relayed to me from the Boy, as I was sitting in the living room with most of the littles (all minus Petey) when it happened.
He brought Léa in our bedroom and he then went back to the birdroom to let Petey out (as letting Petey out first and then taking Léa out while he's free in the room doesn't work really well). After Petey was free in the birdroom, he returned to the bedroom to find Léa on top of one of the speakers of my stereo system in there (a place she most defnitivily should NOT be) making all kinds of happy noises. When she saw that he was back, she screamed (which I heard) and flew back to her Wingdow, which set the Boy laughing (which I heard as well).
He said, it really looked as if she was saying "oh no he caught me, RUN".
