A few years ago, Christopher Doyle promised his daughter that he would get her a pet hamster. However, he failed to keep his promise. So when his daughter wanted a cat, she included his failed promise as part of her argument to get a cat.
To further convince her father to get a cat, she even put together a PowerPoint presentation. One of her arguments for a cat was that pets can lower your stress level and make you happier, which is a proven fact.
Fortunately her PowerPoint presentation proved persuasive enough and Christopher Doyle has decided to adopt a cat for his daughter. That shows that persistence combined with a love for a cat can go a long way to getting you what you want.
