...Is this friendship?

If there is one thing I don't like, it is Hypocrisy. And pretense. Well, that makes two things, but they sometimes are closely related.
The reason why I am writing this is, well... have you ever got the feeling that some people - who talk with you, laugh at your jokes, and are outwardly good friends - do not actually like you though they pretend to do?
Well, I have. And I am sure I'm not the first to think so. It's not as if I'm a complete stranger to all this- it is frequently seen everywhere. ("Wow.. look at both of them... I never had such a good friend when I was like her..." "You actually believe that they like each other?! No way. It's obvious that both of them wouldn't like anything better than to tell on the other person... which, believe me, has already happened.." Not exactly like this, but on these lines..)
In fact, even I have been accused of doing so.

Let me make one thing clear- I like bluntness and honesty. I prefer it to all the sugar-coated lies and smoothing over that other people do. And when I treat a person whom I personally don't like well - it is out of common courtesy and not because I'm trying to pretend to be that person's really good friend just because he/she has good social connections/looks/popularity/(fill in other silly reasons..)...
However, this certainly does not mean that I go to every single person I don't like and go scream in their faces about what I hate about them (though sometimes I have been tempted to!). Luckily, the number is extremely small- so even if I did there would be little chance of a sore throat later on....

One of my faults (or so I've heard) is trusting people and what they say too easily. Even knowing it, this is probably a practice(?) which I haven't yet stopped. (People in doubt can always ask my bench mates who would only be too happy to give their testimonies (read exaggerated versions).)
And the worst thing about this? When you trust people enough to tell them something you would have never even thought of telling someone else, and later finding it spread all over, and finding that it was that person who actually did it, and not someone else's "lucky guess" as you hoped in the first place.

I know that this is getting a bit emotional, but this is actually what I feel. Pretending to like someone isn't going to get you anywhere; after sometime true thoughts will show. That is inevitable.
Friendship is something which should be based upon true liking and willingness to help each other out; not backstabbing and pretense.

I remember once seeing this quote somewhere on the internet.. and thinking of how true it was:

"Some people are like pennies: two-faced and worthless..."

Have a good day!
