Absolutely.  I think I get what you are saying.  I have always felt that I was allocated to the wrong family - I just couldn't seem to see where I fit in. My sister teased me when I was about 5 that I had been a twin and the family couldn't afford two babies so they gave the other one away.  For a while the whole world made sense - I felt weird because I was was missing my twin.  After my Mum found out she told me this was just nonsense and I had never had a twin so I used to spend time knowing I was an alien on a mission to understand people and I used to sit outside on the verhandah looking for signs for someone coming to pick me up.  (Too much Dr Who perhaps?) Oddly enough my Dad used to come out and just sit there with me and after a while we would talk a little. 

I still don't get the point of why I am here. I don't understand what we add to the world - except to create mayhem and pollution and disturbance.  We seem to do a good job of proving just how dreadful we can be to each other.  But it all feels a bit superficial and pointless - we are born, we live we die.  (I am an actively practicising aethiest) But it isn't the religious stuff that gets me  - it is always the question Why?  Why have we evolved to this point and not know what it is that we have as a purpose?

And then, I can meet a couple of people and instantly we click and seem to be on the same wavelength and it sure feels like I am part of a broader community.  I know this sense of being so different isn't really special unique and different.  I think it is the stuff about being a little bit fey that I enjoy most - at least it feels right and I can understand where it comes from.  but yesterday I got an email from a close friend who added a note that she finds me a bit scary that I am tuned into people.  So I wasn't offended and just laughed.   At least if being different is useful, I get that as a point.  I don't feel quite the same way when the difference is ridiculed or demeaned as being too caring.  

Anyhow I am not beyond thinking it might all be a very weird dream that has been going on for more than 40 years.
