Help

So my instructor has a littler of Persian ragdoll বেড়ালছানা and the are gorgeous. I have wanted a cat for a long time now and this is the perfect opportunity. Normally those বেড়ালছানা sell for $1000 but my instructor is selling them for $500 and students get $100 off.

My parents have always ব্যক্ত no and they don't even have a reason. No one in the house is allergic to them, our সারমেয় are just as much of an annoyance to the wildlife, our সারমেয় don't care about মার্জার and our সারমেয় shed heaps of পশম anyway. Plus we live on a farm and we have mice in our stable.

How can I convince them?
