Couldn't they just shout?

Last night at dinner the four of us were talking about our summer vacation plans. SJ and I were telling the kids that in Belgium they can get HUGE waffles for snacks and in France they put chocolate in their croissants. It was fun watching their reactions to these things they haven't yet experienced, but we know will delight them. Then L turned the conversation to when we will be traveling to China. As we have said a million times before, we explained that it is not going to be for a long, long time. L needs to have her 5th birthday and B needs to have his 4th birthday before we can start thinking about our China trip. Here is how the response went:

L- “but daddy is going to China soon.”
MOMMY- “yes, but he is going for work and we have not finished all our paperwork for our little sister yet.”
L- “But couldn't he just bring home our little sister?”
MOMMY- “No sweetie, we need to wait until China tells us to come and get her.”
L- “But couldn't they just shout?”
MOMMY- “What?”
L- “You know, like this...COOOOOME AND GET YOUR BABIES!!! They could just shout really loud and we would hear them.”

We all had a good chuckle and then re-explained the whole process of paperwork, waiting, and referrals.
