Shadows are interesting. They have a reputation of being related to darkness, evil, mystery, etc., but not always. The common phrase, “they cast a long shadow,” has to do with a person’s reach and influence, but is used most commonly after someone has past away. The shadow cast by a tree provides cover from the heat of the sun. We give the shadows cast by trees a different word – we call it shade.
In more recent years shade has taken on a negative connotation, too. To “throw shade” is to talk trash about a friend or acquaintance. When someone throws shade they publicly denounce or disrespect someone, in such a way that onlookers understand the thrower (not the recipient) to be the uncool party.
Regardless of context, or popular vernacular the words remain.
They are the same and essentially do the same thing. They cover.
There will be times when we can find cover in a shadow. We can cool off in the shade. When we are in the shadow we should use the time to rest, prepare, practice, and learn, for there will be a time when the shadow is lifted, and we are sent out into the light. Then we will be the ones casting the shadow.
