4. You are not right!
We know that none can be right all the time, but there are nicer ways to say that, instead of saying “You’re wrong!” right in people’s faces. What they might hear or understand when you are telling them that is that they don’t know anything and that they don’t have any value.
Before jumping to conclusions, ask further questions, try to understand them, and if you don’t agree with them, say it in a more discreet and respectful manner. For example, “Me, on the other hand, I believe that…”, will surely work out better.
5. I told you so!
This one is usually used when there is a contradictory situation going on. However, nobody likes being told, “I told you so!”. It is possible that these people are already in a bad situation, and there is no need for you to shoot a horse that is already dead.
You should help other people out, not bring them down. Ask them what happened and what can you do to help them.
