FRIENDLY OR JUST FRIENDS

When did the relationship between family and friend get so complicated ?, if someone wasn't family you'd still treat them as if they were. Your personality wouldn't vary depending on who was your audience, what you saw in someone would be what you got when socialising with them. So you would be known and accepted for all your good and bad traits without feeling unsure of what was really going on in the other persons mind. Are we so afraid of what people would think of us that we just play it safe when attempting to open up? Cant we just let people like us for ourselves ? because the fact remains you can not please everybody, so you must work out from the start are we true friends or just pretending to be friendly? The act can only go so far before you realise you may think your pleasing your friends but your losing yourself in the lies.
