It's funny when everyone knows what's going on but nobody talks about it. She knows, so does her mom, and his mom (who's really smart) and him... and so do some others. But everyone continues playing their part without mentioning the obviously possible and eventual. Only one person merely hinted at it, but they went on in conversation as if that wasn't said. Of course they knew it was. But what do you reply to that? Except for wishful thinking... They know that it will happen at its due time. In the meantime, they just laugh a lot and keep it simple.
