I don't have my own piggy bank. The first reason why I don't have one is because I won’t be able to touch money until it is full of them. Besides, I can’t even use the money when I really need. Secondly, I won’t be able to know how much I’ve been saving money. In my opinion, the best way to save money is to put them in my secret place in the envelope so I can take them out and count them how much I’ve saved anytime. In fact, I have been doing like that.
