This quote compares gossip to glitter, which is tiny, shiny stuff that sticks everywhere. When you spread gossip, it's like scattering glitter. Once it's out, it's tough to put back in its box. Gossip spreads fast, just like glitter spreads all over when you use it.
Like glitter, gossip leaves a mess behind. You can try to clean it up, but you'll never get rid of every tiny piece. Gossip can hurt people and damage relationships, just like glitter can make a mess that's hard to fix.
So, remember, it's best not to spread gossip in the first place. Once it's out, it's hard to control, just like glitter. Keep your words kind and positive, and you won't have to worry about cleaning up a glittery mess of gossip.
