This will be a short post.
It has been drummed into my head, while writing, to be concise, show instead of tell, and avoid unnecessary words and redundancy.
Lately, one of the things I have noticed while doing critiques is the use of the sneaky little unnecessary words: “up” and “down.” Did Bill “Stand UP and walk to the window”? Or, did he just stand and walk to the window? Is it possible to stand without it being up? The corollary, can you sit without it being down?
Did you go “down to the store” or “to the store?”
Simply, if it is not possible to do something without it being “up” or “down”, leave the word out.
