not necessarily sociopathic life-altering lies, but little ones.
for example, let's say you pissed on somebody's salad by accident, you can see that only one drop landed on a lettuce, so you pick the lettuce out and it's good as new. you could tell them and they wouldn't eat it, probably lose their appetite and be upset. or, you could not tell them, they'd eat it happily with no bad consequences, and everything works out fine.
lying really is for the best in certain situations, right?
