It seemed likely that Danny and Annie had approached their mother for training because they had noticed how busy Rain had been lately. Rain was dedicated to spending quality time with his children, devoting at least two hours every day to playing with them. However, they hadn't asked him to provide them with training, even though it might have been something they desired.
This choice on the part of Danny and Annie could be seen as a bit sad, as it indicated their awareness of their father's busy schedule. They were showing thoughtfulness and consideration for his time by not adding more demands to his already packed agenda. Their decision to seek training from their mother instead of Rain was likely driven by their understanding of the importance of his responsibilities and the desire to ease his burden.
