Mine is very bossy

In the previous chapter, we read that The brothers were having a normal when they decided to decide on a name for their gang when:

Robert: I have a name in mind

Robin: What is it?

Robert: The cool brothers!

Robin: That's more like it

Robert: Now come on it's almost time for our next class

Then they went to their second class, time went by and it was time for lunch. Three of them entered the cafeteria. David, the boy from their class was waiting for them. They went to an empty table, Robert didn't sit:

Robert: You guys talk, I will fetch some lunch for you all

Then he went to the food area. After he left Robin introduced Mike to David and David to Mike then David said:

David: It seems you three look after each other

Robin: That's how brothers are, right?

David: Not all adopted brothers are like that, mine is very bossy

Robin: Your bad experience doesn't mean that everyone is like that
