Unpopular Beings

Today we went to Vlad's birthday, me and Gogo. A girl and a guy there clearly do NOT like us. They treat us like "locals" or even "natives", no idea why they do that...Gogo and I are not that traditional perse... but they do.
So anyway, Gogo is so troubled by it.
Didi, did we do something wrong, something that offended them?
No we didnt, they just dont like us, 3adi, the more you are yourself, the more people get to dislike you. (me)
Well, maybe we did something that offended them, like...I dont know just something, there must be a reason why they hate us.
I dont think so, I think they just hate us because we're really strange people and they are scared of trying new flavours.(me)

And that was it...
And the question is, Why care about people's opinion if your own opinion, and your close friends' opinion is much more valid? Why do you think your friends compliment you when, in fact, they are the ones who know you best?
