Real Friends are NOT extensions of ourself.

REAL FRIENDS have their own minds, personalities, or characters. They are individuals. Unique in his,her, or their own way. They are (or should be) capable of determining between right and wrong and bge able to make decisions for themself.

When our friends disagree with us, or or our reasoning, we might take that 'personally' as an affront to our sense of dignity. BUT the fact is that they are right to do so, because we do not choose our friends to become clones of ourselves, nor to affinitise with everything that we say and do.

Where would be the interest and respect in having 'a nodding dog' as a friend. Friends become many things to us, and their right to disagree is just one of those.

This does NOT make them 'a back stabber' nor does it make them 'unfriendly' .. it makes them what we as intelligent human beings chose them to be .. UNIQUE INDIVIDUALS IN THEIR OWN RIGHT.
And for that we like them and or love them, each and every blessed one!
