Pro: She's a Princess.

Con: She may blast you with magic.

Pro: Given that she's a Pony she is still attractive.

Con: She's been around for over 1,000 years.

Pro: Age is only a number, some people keep their beauty. I mean look at Olivia Newton-John.

Con: She's a pony.

Pro: She's a "Pony" not a pony.

Con: She's a pony.

Pro: She's obviously a sentient Being with Hominid intelligence and knows how it's like to be Human and make mistakes. I think it was Mark Twain who said, "Human's are the only Beings that can blush because we're the only ones who can." Or something like that? Anyway, a "Pony" can do the same. Probably because their fur is evolved to change color, depending on their emotional state, to which they can show their embarrassment, humility, anger, or love.

Con: She's still a pony.

Pro: In addition to the previous Pro, she is able to communicate with you unlike "ponies." She doesn't whinny or neigh but she would probably still do that cute noise through her nostril's ponies and horses tend to do, but even that is a rarity. She actually tends to do that when she's angry or upset which is also a rarity since she's always so cheerful and loving.

Con: She's a po--*THWACK*

Pro: Go away Con, your argument is one sided!
