I can certainly relate to the hiding and responsibility aspect and it's a good thing to look out for that. "What do you want to eat/cook?" is a good and simple example. But what I also realized is that you don't have to have an opinion about everything just because some else is interested in something. And there are also people who on the one hand might complain about you not participating actively in a decision process while at the same time those people may not like what you finally say or they can't easily cede responsibility or decisions to someone else. To not get a wrong generalized picture of yourself by these questions and by what others see you might also want to look at situations where you would naturally react differently. For example I saw you love to make music and videos, and in that creative process you're probably not indifferent towards decisions at all i guess. But it sounds to me as if you're already aware of that since you said it's rather small things that come with a little indifference.
