Sadly your not going to like my third answer answer...
As a child I was 'the little builder' so I had to go to the garage to build my stuff - but even with the grage outside I would usually bring to tools to the bedroom - yeah my mum loved me for it, especially when I would build oily things on the bed.
A motorbike at 12 - pretty obvious - the family would take my 'latest' motorbike (I had 7 in the space of 4 years), when we went camping (or is it we went camping because I had a motorbike?) -camping and scouts in itself got me out too - to the point where I love camping - but I realise that camping is much better in a small group or by myself, actualy scratch the small group, by myself or with a spouse.
Marijuanna. --I couldn't have my parents knowing.... but even the use of an illict drug didn't push me to go outside enough - I got cocky and thought I could do it indoors, in my bedroom - with my brother in it (what's that smell) ,, when I stopped smoking I went back to my old self.
--Everything was in my bedroom... the library, the workshop, the Datacentre, the music centre(instruments and stereo), the design studio, the study room...I actually built custom furniture in black/white grey tone at the age of 11. (My father was a chippie - not that he helped - alright he preped the spray gun the first time) - I think that my Autsim was cured by simply turning me into a Serf - I had to work for my parents at the age of 7, just like an apprentice in the middle ages - come to think of it, I wonder if autism existed in British Coal miners town at the turn of the previous century?
--- As an adult though and now working as a chippie.. my typical day is working and then sitting on the computer - I think this has become my hobbie... today I 'fiddle' with the computer and waste my time on the net. -it's very addictive you know - I am telling myself to stop being on Wplanet and just get over it .. so you have ASpieism - I promise myself I'll stop in two weeks - let's see who I go!
----When my long term friends ask me to go somewhere - not so easy... they actually tease me about it, I am famous for saying 'I don't know' whenever I am invited to an event... on the whole for the last ten years I have been forced - my friends realise that my overall appearance when I am with themm seems to them that I am enjoying myself, so they have beomce adept, at just showing up and telling me to get in the car, let's go, your going and that's it -- is usualy what they say. --So yeah I am lucky! , if it were upto me I wouldn't have gone anywhere outside my bedroom, and wouldn't of had a 4 year relationship, heck I wreckon I would still be a Vig.
---Sometimes I want to go, but know what to look forward to... a time of unawkwardness and discomfort ... I am usully very tired after being anywhere with my friends, even small little outings... but sometimes I'm not, where I feel that - oh that was better than usual! ,it's those better than usual feelings that yo have to take away with yourself, and hopefully gain somesort of hope for the next time you go out - though fo me I have had tons of good times, and still feel like I just don't want to go.
