One of the things that has gotten popular lately is the concept of "repurposing" items. Instead of throwing things out, you use the item in another way. One example of this is to take old Christmas cards, cut out the top into a star shape and use it as a gift tag. I've been repurposing since I was young.
When I was in fourth grade, the toilet in our home started acting up. Apparently the flapper in the tank wasn't making a tight seal. My dad started fixing the toilet. In the course of fixing the tank, he took off the chain that went from the flushing mechanism to the flap that opened up to let in the water and replaced it with a new one.
The chain was left on the bathroom counter and I quickly spied it. I asked my dad if I could have it and he said I could.
I wore it around my neck as a necklace for most of fourth grade.
I just like to think of myself as "green" before it became cool.
