Why do people call me hun?

Im not
that young. And yeah I noticed that too, on pretty much every website with forums and people ask questions about breeding, people always reply with spay her and all that. I told my mom about how we might have to pay $1000+ for C-section emergancy vet visits and stuff. She said well we'll have to wait for when that time comes then. But what if that time isnt when Miley is ready (in heat)? I know it is good to wait for her second heat to start or when shes 2 years to breed her. It is so hard to wait though. And I really want to do something with her, like show her, breed her, etc.
