I feel like "what if you donate an hour or more a week to this child with whom you have no particular relationship" is a pretty big ask for this, and it's good for kids to learn that LOOOVING the kitty does not mean that it is YOUR kitty or that you get to do things like looking in the neighbors' windows, we still observe interpersonal boundaries. Hearing no can be pretty upsetting when you're 7, and also it is totally necessary to hear no when you're 7 in order to be a reasonable person when you're 27.
