Omitting is lying when you know the information withheld will change the outcome of a persons perspective on how they should weigh their choices on how to maneuver the situation. It can be considered as manipulation. Withholding information deliberately is deceptive. So yes omission is lying!
No shade something I try to be every day is a good person. I’ve been through a lot, I’m not perfect, and I know I’ve hurt some people’s feelings, and I’ll hurt a bitch’s feelings again if need be, but I always want to navigate through this world with kindness and happiness FIRST .
