Children do not ask to be born. They are not indebted to you for 'bringing them into the world'. Parents are indebted to their children to provide for them, raise them, guide them and love them. If they can't do that, they shouldn't be parents.
People misunderstand glitter. Treat it as a hazardous substance, not unlike a can of polyurethane, and generally you will have good results. Follow up by sealing it with polyurethane after for full effectiveness. It is not that it is not a child's toy, but that children miss half the experience, as they are not the ones getting glitter sealed to their skin with polyurethane for the better part of a week. They are fully capable of learning proper handling, and with this knowledge, nobody need deal with loose glitter ever again.
