"So... you're the new guy, welcome to the house... I guess"

Red Guy greeted from the table in the living room of the house, with a cup of coffee in his hand.

He seemed to be aware of your arrival to the house, so he was relaxed about it...

"You can sit if you want... or you can, I don't know, stay there..."

He didn't really know what to say in this situation, at least he put the minimum effort into trying to give you a decent welcome now that you're part of—the family?
