Both my Son's are interested In my hobby and when I have the scopes out and they happen to visit they have a look through the eyepiece and so does their partners and yes they are impressed with the views, but at an early stage in their lives mid and late 20's. Having said that when I was in the UK my eldest was with me every week at our local astro club until we moved abroad back 2005 so he would have been 15. The problem today is if you want any information you go onto the internet, Yet back then information was limited and you relied on literature.. I did have a Meade ETX 70 with tripod and travel sack basic scope which my son pilfered last year can I borrow it never to be seen again albeit it was covered in dust . So maybe a change he wants a bit of me time. I have no qualms with that. I think that a hobby like this is either with your parents or later on in life when you have disposable income.
