Lets say you are talking to someone and they are saying something that you disagree with, like really disagree with. But you dont tell them. You just pretend to agree with them with some non-commital nods of your head and a few unintelligible mumbles. You dont want to face the challenge of presenting your disagreement in a diplomatic way. So you stuff it.
You look at it this way for a minute, “now I know that I dont agree with them on this topic, so I wont bring it up again, lucky me I have the power now.“
The question is are you doing them a disservice by holding back your opinion, which may have the ability, if presented with grace, to affect their opinion?
Depends on the person you are talking to I suppose, their personality and relationship to you. It also depends on you and your personality. I probably stuff more than the average, since I am actually very opinionated but rarely up to the task of really putting it out there. Opinions run through my veins instead of blood. We really must pick our battles carefully though.
We all hate to think that someone is doing this to us, not admitting what they really think and letting us blabber on in error or folly, but they might be.
