Being honest and telling a lie at the same time

I find myself telling a lie to a person to get the truth told. If being friendly is how i get people to do what I want then it is actually manipulation and I am acutally feeling like a liar.

What if my being nice makes people happy and like me but I still feel bad because I think they are naive and stupide. Somehow this makes me stupid as well.

If I assume that someone is stupid, I guess this person has the same view on my intelligence. This all may not make any sence to someone reading this, but it makes perfect sense in my head.

How you do anything is how you do everything
