I have noticed from my own experience and from watching others that women are "carry alls."
We tend to "carry all" we can. An example is when we take groceries in. We try to limit the number of trips between the car and the house by "carrying all" we can each time. When possible, we'll only make one trip.
Meanwhile, men will take one or two items in at a time. Thus, we usually wind up helping them. Guess they've got that figured out.
I think it's in our nature somehow. I've tried to take fewer items in at a time, but I always end up with both hands carrying as much as possible. I don't want to waste time going back and forth.
I also see this in a lot of the characters I read about. They try to carry all the responsibility of solving the murder, while balancing their everyday life.
Are you a "carry all" person or can you limit how much you carry at a time? Does it bother you to make numerous trips back and forth between two points?
