Sorry your aunt has left you with so many lingering questions, unanswered. It seems kind of unnecessary to tell you this now. I suspect it might be the time you remember with the gadgets. And holidays get more difficult when you're older because you have different priorities. And as a teen, you get so self conscious that you do sometimes act weird and embarrassed.
I remember passing on an opportunity to go on a family holiday to Jersey when I was 15. I wanted to change my mind at the last minute, but the travel company couldn't accommodate an extra 1. I'd opted out because dad was a bully making my life hell, but I missed a really great holiday and of course, dad was nice to us on holidays. So it was my loss. And a regret.
I had times when I wish I could have articulated my feelings and didn't - actually, couldn't. I think I was autistic, but am apparently now so good at pretending to be normal, they don't consider me as such.
