A mineral is a naturally occurring inorganic compound, which have definite chemical and physical properties. It form as a result of geological process. Luster is the physical property of mineral that refers to the reflection of light by the mineral surface. The luster of a mineral is dependent upon the surface area of mineral and the type of incident light on mineral. Metallic minerals show more luster that is more reflection of light than non-metallic minerals. More intense the incident light more will be the reflection.
It is because little kids and toddlers copy everything that they see other people do. If they see you doing something, then they think they are supposed to do it too, and they copy you. Also they are “like sponges”(that’s what my mom says) and “soak up(/remember) everything”.
