Is it normal i that i am so comfortable with strangers?

Is it? if i see somebody walking along the street i would have not problem at all with just starting up a random conversation with them! its something i actually like to do...? i am not saying i would just go onto some random strangers car or house but that's how you make friends. By talking with strangers.I don't see why people have such a habit of only making friends with people from there school, or their friends friends.I don't think that's really a healthy way to live and i find independently putting yourself out there is much more better.

I tend to put myself out there quite often. More then others. for an example in school i will never deny someone of friendship. I think that it is a great thing that they are reaching out to me and being kind, why not be nice back? I am going right now to 3 different party's this weekend that my 'click' are not invited to. They probably don't even know half of these 'strangers' that i am so close to! i build strong relation ships with everyone. you have much more fun that way in my opinion too.

also, you never know where making a random friend will take you in life! Not saying i will know the next justin bieber or Michale jackson personaly just by making a random friend but you never know. Its the little things that matter.

So here is the thing. Am i weird for having this perspective on life and everything? or is that just something that not many people think about. I have a habit to over think just about everything and well this is one of them!
