Truth matters. When we manipulate people and lie to them because we decide that it is in their or our interests then we take something from them. We treat them as the means to some other end and definitely not in their best interests.
We might delude ourselves by saying that it is a little white lie and we don't want to hurt their feelings or we just don't want to tell them the truth.
In every case we are not being true to ourselves and getting in the habit of not telling the truth has an impact on us and what we hold to be important for us. Eventually most lies get discovered and we have at that point lost an important ingredient necessary for any kind of relationship.
We are no longer trustworthy.
Once lost it is almost impossible to gain back again. It is much better to say nothing than it is to lie. Even better to tell the truth and we need to be very careful that our truth isn't just gossip. If we don't know personally because we were involved in the situation then it is only gossip and remember always that is also only our interpretation.
Is it possible not to gossip or lie?
