I appreciate that.
We try to plan but are definitely not stranger to seeing how it goes.
Our 18 year old son is autistic. So because he is an only child, no friends and isn't like other kids his age he still isn't allowed in the teen/kids areas because he is 18. Maturity wise though he also isn't an adult. He doesn't understand slang and sarcasm etc. So we are trying to plan for his sake.
What can be difficult for my son is having too many options or something, he just can't choose, so this usually involves a lot of pre-planning. (If I were to throw him in a movie theater with 15 movie options he would literally stand there for two hours not knowing what to chose, but if you narrow it down to 2 movies or something that could work.) With that we also know that some things just may not be for him and we may need to re-direct. He is very smart and some might consider him higher functioning but he is actually moderate.
