Many things are revealed with gender
We don’t want to assess, but the parties which are thrown to reveal the gender of the child are the stupidest sensation in recent years and that is indicating something. We may carve you if you don’t know about this.
But for the one who doesn’t have any clue these parties are thrown by parents-to-be to disclose their child’s gender. We don’t know why anyone would care but it’s up to them. We only have a problem when these people abandon environmentally-hazardous, and potentially dangerous, plastic pieces in public gardens without cleaning up.
