Okay so. When I was young my family and I needed to find bags to toss our trash out in. And we had the bags from when we brought groceries. So I had an ingenious idea: That we could reuse them through finding a different use for them. To put trash in them and throw them into the trash can.
So you see: Recycling doesn't only mean re-using something. But that you can use it in a different way, for a different purpose.
Later on I had a prescription and obviously plastic takes money to make. So I brought my pill bottle from the previous month to the pharmacy and they refilled it and put a new sticker on it.
