Oh, and, I know that problem, so, I won't judge you if you get it wrong because of memory stuffs!

I can accept hand-hugs or wing-hugs, it usually helps if people ask. Online for example, "hugs if wanted" is a good way to say it. Then, I don't feel like I have to accept. In person, just ask me "is it okay if I wing-hug you?" etc. That should be fine. ^v^

Thank you for asking!
