It's made with high quality materials, and I'm going to be wearing it every winter for the next fifteen years.
I convinced myself that I deserved to own that sweater, and I bought it. Now, I regret it. It's going back to the store tomorrow.
I thought about it for exactly half a second, and then I decided not to buy it. I can't afford to buy something that expensive, especially since I didn't need it.
The sweater fit perfectly and makes me feel amazing, so I bought it. It really wasn't a hard decision to make.
