A bubble gum.
I thought of it just the wrap of a bubble gum. But I wasn't expecting that it's with the bubble gum that I've chewed. Sounds weird but I was still a young guy when it happened.
But how come that a Chewed Bubble Gum stays in your wallet ? if that is a Unchewed that is reasonable but what you have >?lol that's really weird
When I was younger, our teacher taught us to keep our things put into our pockets if we haven't seen any trashcan.
At least, that's what I can remember on how I kept a bubble gum on my pocket not wallet.
