1.) be born with a deficient brain that cannot intuitively understand and replicate social behaviours and skills

2.) rely on the natural autistic brains tendencies such as only talking about your special interest, not showing eye contact, having a monotonous voice, being unable to have back and forth conversations and instead rely on info-dumping their special interest, being unable to tonally alternate their voice to portray different emotions, stuttering, etc.

3.) get bullied and harassed for that behaviour in 2.)

4.) Develop extreme levels of trauma from these awkward social interactions and resultant bullying and isolation, which inevitably leads to building a mindset of protectionism and maintaining one's social status via abstaining from social interactions in order to prevent bullying (i.e. becoming introverted and anti-social)

5.) have lifelong social anxiety

6.) turn 18 and start panicking about insane lack of experience leading to intense self improvement and social exposure therapy in order to counter the social anxiety

7.) completely fail at the social exposure attempts due to the autism and due to the missed out 18 years of social development

8.) get extremely depressed and even more socially anxious
