CATS DON'T EAT CARROT
Richard just wanted to tell Misha that what Kiandra went through was very difficult and not as easy as he thought, especially the matters involving money.
It was very difficult to discuss money when Misha was so used to having a lot of money. Even their point of views were so different, because the definition of 'no money' or 'difficulty making money' was not in the vocabulary of Misha at all.
Therefore, Richard wanted to tell him this, trying to make Misha see more clearly that 'money' was a privilege that not everyone had, a privilege that he had and not everyone could enjoy.
However, it seemed that Richard was in too much of a hurry to show this view so Misha read it pretty quickly.
"Life as a single parent is very difficult, especially when you have to fight alone to support yourself and your children."
Richard wanted Misha to understand this.
