The line between self-confidence and arrogance

The same thing about Cow X, why do some people feel arrogant, some people feel that he is very confident?

Here's what I think:

The line between self-confidence and arrogance lies in the tendency to show willingness to help others.

As an example:

Also talk about the experience of a bull x, arrogant people can make people think you have what is the relationship between Ox x? You're showing off to me!

Self-confident people will feel that this cow x experience is nothing, if you want to achieve, you can, my experience can provide you with help.
