It might not be an ASD. Can't tell until the team do their work, of course, but I can generalise a bit..
I'm sociable with people I know. And my goodness me I have an imagination (though it's a bit odd!), and I can be affectionate on my terms. And I'm aspie as hell itself - right off the scale on most of the things tested, and well on the scale for the rest too.
The thing is, our sensory world is such a nightmare unless we can plan it. And we have no people-recognising bit really. So if we a) know who someone is and b) know enough about that person to be able to predict what they're about to do/say, then we can prepare ourselves for any sensory issues.
Eye contact can be a big one, because it can be wired directly into the "arrrghh! scary monster!" part of the brain.
Touch can be a big one, because if we're not expecting it, it's like being punched.
Sounds can be a big one - a noisy group is like a wall of sound to us, and totally overwhelming.
So it's not that we can't be sociable, or friendly, or imaginative, or affectionate, it's that we need to test each step of it so very very carefully before we know if it's safe or not.
A noisy group of strangers? Urk - anything could happen, and the noise hurts.
A sudden unexpected hug from someone we hadn't realised was there? Hell itself.
Meantime, our brain stores hobbies in ridiculous detail in the bits it's supposed to store the people info in, so we can get obsessed with things and patterns etc as they seem hugely important to us. And our language bits don't want to work in ordinary ways at all, so we can seem pedantic, little-professorish, very literal, etc. Or not talk at all well/or indeed at all.
Just examples, but it explains a lot about the sorts of problems and ways we try to solve them.
People had this idea that all autism involves very distant, unimaginative people. That was before we started writing about ourselves and revealed more about what we're actually like.
