It's not rude. It's obvious people don't care.
It's more money in your pocket now, if your a kid. But, it's less money in your pocket later for your parents or an adult. "Kid's have the best lives." Enjoy your lives now kids. Because it's eventually going to get much, much harder. One day, you might even think like I do about saving money.
Unlike other people, I do care. I'm not a little kid anymore and haven't lived with my parents for many, many years. What I have is what i've worked darn hard for. And i'll be darned if i'm going to just give my money away to someone else, when there are ways I can keep more of it for myself.
