O.O

I was wondering, who the hell came out with similarity and congruency? I don't freaking understand. Triangle is a triangle, why must they be similar? I think they're happy being one of a kind and not being similar to other triangles. Why must a triangle be congruent, they're the same then let it be, why must we prove that it's the same when, it's the same -.- what's with all those mathematicians, why must they prove everything, prove this is similar, prove that is congruent something is more than zero and many more. Oh damn, I tired of all these. T.T Headache.

We should stop proving, there isn't a need to have evidence for everything we do, isn't it? If you're not tired of proving, I am.
