I honestly hate this. It's no wonder a lot of us on the spectrum never learn social skills. Our families think we're incapable and because of it we never acquire social skills that we could attain. We get babied until the point where we can't do anything ourselves.
I have to agree, this used to drive me insane. At the moment, for my passport, I did need their help so I'm not worried about it so much lately...but when I lived in the same state as my parents, it was a common thing. She's backed off for the most part but there's still a few things though that come up randomly.
My mom would for a long time open any mail I got. Bank statements, anything, so long as I wasn't there. This used to drive me insane. She's done this a few times recently, and commented that I have an overdraft on an old deposit account for about $30. Since I'm obviously moving overseas and been living here for six months, I said it wouldn't matter (no one else's name is linked to the account), but she still dug through my bank account numbers and deposited the money. Obviously that's difficult to complain about. Even though it was one, completely unnecessary, it was the invasion of privacy was enough to set me off into a fit. I ended up just looking ungrateful and paranoid.
The recent one though is her setting up an airline miles account with KLM, for my recent flight to the UK, without bothering to ask me if I already had one (I've had one for years). Since they won't let you transfer miles unless you reach a certain amount, which a 30 minute plane ride did not qualify for. Now I can't use it or move them, and have two accounts for no real reason.
Also the mini-arguments about flights. She often arranges the flights for me, but will argue with me about the details of how long I should stay or when I should go, when on her end it wouldn't matter in any sense (cost or convenience)- but on my end it does make a difference, since I'm the one actually traveling it.
It's always little things like that. She means well, which makes it somehow more frustrating because I feel like ass complaining about things like that...but it just annoys me to no end still. There's always a reoccurring mini-fight of "just let me do it, I can handle it, I want to figure it out". I'll ask for help if I need it, and will appreciate it, but I hate forced help when I don't ask for it, if it makes any sense. It does actually make me feel babied and disorganized.
