Canter

My cousin is looking into purchasing a horse, but I'm not entirely sure he's considered the attention and care that such an animal deserves. He seems to have developed the idea after a weekend visit with my Saddlebred. He has the financial means, but...

I don't think he has the right temperament. He's not the most patient of people, and he has somewhat of a short attention span when it comes to long term projects. I'm afraid that he'll show some initial enthusiasm, but quickly lose interest. I don't want a horse to be put through something like this, but at the same time I worry I'm just being unfair to my cousin.

I don't know what to say to him without sounding like I don't believe in him - and if I'm not careful, he might rush into buying a horse just to "prove me wrong".

Am I just being paranoid? What can I try saying to him to impress upon him what goes into horse ownership without it seeming like I'm accusing him of incompetence?
