This is a funny question! I can understand why it occurs. But you ask this because you proceed from the idea that there are situations when a person needs nothing to have. Women do not have such situations.
The fact is that they always, at any time, even at the most unexpected – may need something handy from a women’s handbag. From hygienic lipstick to a headache pill. Do you often carry a pack of pills with you? True, no. And therefore, you always ask for a pill from a prudent wife who always carries them in her bag. Therefore, the question of who is doing the right thing is open. Women are always ready for unexpected situations much more than men.
Another explanation is that a women’s bag is still an accessory. This means that it complements their fashionable look, makes it complete. If you see a girl with a bag at the theater, you’ll hardly have a thought that she might have something wrong. However, if you spot a girl with empty hands, I bet you will find her strange.
