Julie pretty much adores her big sister, and she thinks every joke she makes is completely hilarious. It's funny, because she obviously likes me (and most of the time her father too ;)), but it's her big sister that she's actually crazy about. Lucky for Julie Rosa really likes her too, most of the time that is. Unfortunately I can never really profit from this Big Love Affair between the two of them, because each time I try to exploit it a little -for example when I'm busy in the kitchen and Julie starts crying- by asking Rosa if she could please go to her sister to entertain her for a little while, somehow Rosa isn't interested at all to play with her little sister. No matter how often I say 'Julie would love that Rosa, she likes you so much, she thinks you're hilarious', Rosa will only do her special tricks and jokes with her sister at her own terms and time. These kids seem to have some sort of radar for you wanting something from them... So that they can do the exact opposite ;).
