your friend has older brothers....

You were a teenager who had a friend; she invited you over to her house. When you arrived, your friend gave you a very warm welcome. At night, she told you that you both should go lock yourselves in the guest room. Once you entered, she locked the door. You asked her why "Why are you locking the door?" She looked back at you, looking a bit uncomfortable, and told you "I have older brothers, it's just in case."
