What do people in the street think about going out to travel with their girlfriends, but their girlfriends have to take their younger brothers?

What will people on the street think? I can understand what people around me think. With all due respect, if you travel with your girlfriend, people around you won't care too much about you with or without her brother. From your point of view, if you and your girlfriend are willing to take your brother with you when traveling, it means that you have been regarded as a husband and are willing to introduce you to your family. If you want to travel, why not get a room first and take your girlfriend out? Of course, if you really don't want more than one light bulb, you can just tell your girlfriend. From her point of view, you should not refuse. I can only answer so much for the time being.
