You shouldn't judge other people's choices
Barney is sitting on his front porch when his much older neighbor, Tim shows up in his new sports car.
Barney wants to comment on the sports car.
Barney tells Tim that the sports car looks amazing and sleek.
Barney tells Tim that it's odd why he would buy a sports car at his age when he needs retirement money.
Tim is happy that Barney commented on his new car and told him that he loves it.
Tim is annoyed that Barney is being snarky about the way he handles his finances which is none of Barney's business.
