That would be so annoying.
Oh, and I thought of another quirk I have. Ever since I was a kid, I've always thought it immoral to put a MOC's mask/helmet on until they're finished. I feel like the character is "activated" when they've donned their mask, and therefore doing so before they're complete is like waking somebody up in the middle of an operation. I'll even pop the mask off if I need to make alterations, minor or otherwise. It's super silly, but I just can't shake this feeling off. Toy Story f****ed me up, man.
