(it's) nothing personal

(This is) not based on emotions, subjective motivations, or personal biases; (this is) not meant to offend you; (this is) not a personal slight against you. Though it can be truthful, this phrase often tends to be sarcastic, insincere, or unconvincing in usage or reception. Larry: "But how can you fire me after 20 years' service, just like that?" Matt: "Nothing personal, Larry, it's just the way the business is moving right now." It's nothing personal, Dad. I just think it would be easier for all of us if you weren't at the wedding. Nothing personal, but your voice is really getting on my nerves.
