I can't believe people throw away pennies!
What about throwing pennies away bothers you so much?
I just hate the thought of throwing money away. I'm actually an extremely economically aware person.
It sounds like you've got a good head on your shoulders. Being financially responsible is a very good trait to have and helps you have a secure future. Kudos!
Even if it's something as minor as a penny, I will keep it and save it!
Every little bit adds up! You are wise to be saving money, even small amounts. Eventually, you will have saved up enough to buy yourself something nice.
