Who am I? And if yes, how many?

Certain people make you feel in a certain way. It's not just about feeling good with someone or not. Sometimes you might feel good with a person in one moment and bad in the next second. It is just something they say or do that suddenly depresses you.
People have been telling me i give them the impression of not being smart enough, of not being interesting enough or of being ridiculous. At the same time, there are people who actually give me the impression of being arrogant, being snobbish, being vulgar or being not smart and not interesting enough.
So easy to blame the person who makes you feel bad for making you feel bad! But actually, i think, when you are hurt by any of these impressions, then it is, because you think they are true.
So if i make you feel ridiculous, it is because you yourself think that this is how you are. Even if, objectively seen, it might be wrong or at least untrue.
It's always your own mind, your self-esteem and perception of yourself that should be accused of feelings of inferiority. But feel free to accuse other people for being tactless nonetheless...
