Well, Im glad that some other people feel like that, because it seems like a lot of people on here are happy to be alone most of the time. I sometimes feel as though I am NT inside (I have a need for company sometimes and I can feel very strongly about people that I have got to know, and feel as though I can empathise with people - although that may be only in my imagination), but on the outside I am Aspie (unable to make and keep friends, socially awkward, unable to express emotions or act in socially normal ways).
Most NTs I know are quite happy to spend weekends on their own, but at the moment I am finding them very difficult - maybe because I spend EVERY weekend on my own and Im getting fed up with having noone I can socialise with. It is true that I do like and need quite a bit of time on my own, to do my routines and to relax, but because it is happening all the time, my current overwhelming desire is to spend time with people (well certain of them).
Also, if I find a new friend, or group of friends, I become almost obsessed with them and want to spend as much time as possible with them and become paranoid about missing out on things. I dont think this happens for NTs and it doesnt seem like an Aspie trait either.
