For example, if I say I am taking out the trash, are others correct in saying that I need to specify that I do not want help? Is the statement "I am taking out the trash" too ambiguous to make it clear that I am intending to do it by myself/alone/with no help? Or is it common sense that when I say "I am taking out the trash" it means that I am doing it alone?

Please weigh in, one person says that phrase isn't clearly communicating what I mean and I instead need to specify that I don't want help, while I think it is perfectly clear that I mean I'm doing it alone.
