Like Minds Do Not Repel !

In our school days we had this interesting lesson in Physics that "Like poles repel and unlike poles attract" and then you go home and try that on your magnets you've collected. Yes, it works for magnets not in case of friendship. I say that like minded and unlike minded also attract each other. This might sound gay, but I'm talking about minds not s**.

Friends keep saying that we did this naughty thing and we did that funny thing. Is it that feeling that brought them together? I mean doing bad things at a time or craving to do bad things. I strictly say no, because some of my best friends I've met have the same bigger dream or passion like me. We are like minded. Even though I met some people 2 or 3 years back, we feel very much bonded because they think like me for a bigger and good cause. Like army soldiers bond very easily because they are fighting for their country.
I'm not saying our friendship is boring because we do silly and funny things together all the time. But when I take a step ahead for a good cause, they are always with me and vice versa. This gives a sense of respect and happy that you found some like minded friend who will support you.
Although I'm not saying that it's wrong doing friendship with friends who are not like minded. As friendship has no limits and boundaries.
