Obsession vs reality

Hello All,

looking for some advice… I have known Z since they were 5 years old… myself and many other volunteers did years of play sessions until it got to the point that Z could go to school and many things improved… 

Z is now 19 and trying to find their way in life… doing work experience here and there and applying for jobs etc.

One of Z’s close friends (a volunteer) recently passed away and Z wants to put together a tribute concert in their memory. 

Z is obsessed with singing like Adele, Celine and a few others… they want to put together this amazing full professional concert event in a local park… but the reality is that it’s probably not going to be anything like how they want it to be… I’m not going to lie… Z is not the greatest of singers!!

I try to point out to Z a few things here and there to try to get them to realise how they may need to simplify their project but Z just glosses over it and talks about another element of the project…

Any tips on how to juggle reality vs unrealistic expectations/project with someone who has Autism/Aspergers? 

Thanks!
