Luis and Thomas were in a small group, chatting with a few people that Andrew had seen them with a few times throughout the night. He assumed that they were actually their friends, not just part of the large group of people they had invited to show off to, and didn't mind too much when he wasn't fully introduced to them.
At least, he wasn't pulled aside and introduced to. They spoke to him and about him as if they already knew him, and Andrew liked that kind of treatment. He was just glad that they had friends.
"Max! Andy! What are you two up to?" It was Thomas, and his boisterous voice told Andrew how much he had been drinking. They were speaking to a group of their friends that were partially lounging on some of the couches around, a small table in the center of the groups laden with food and drinks. Luis and Thomas had an arm around each other, attached at the hip and it was cute to see.
