I do not honestly know what she is trying to be when she does this but we all love it!! Here she comes around the corner - binoculars up with one hand, whistle in her mouth with the other hand - and you hear a VERY LOUD whistling going on!! When she started this routine the other day Micah was taking a drink of water - when she walked around the corner, Micah's water sprayed everywhere he was laughing so hard!!! It is rather comical!!!
