In Sheldon and Leonard's apartment

Sheldon, Leonard, Howard and Raj were playing dungeon's and dragons after eating Chinese food, which without exception is eaten on Friday. "you enter the dungeon and you see a vicious fire-breathing dragon, what do you do?" Sheldon declared. The other three (not particularly paying attention) were discussing what their plans were for the weekend coming.

"I'm going to have dinner with Bernadette's parents tomorrow" said Howard, in a slightly worried tone, clearly disappointed at the fact. "I'm sure it's not going to be that bad" comforted Leonard, "it's going to go fine, maybe you just need to spend some time together to get to know each other. after all, it's got to be better than being alone for the weekend like me" Raj added, rather dismayed.

"excuse me, but could we please get back to the game? a dragon is standing right in front of you and you are discussing your weekend plans!" interrupted Sheldon. "to be honest, I should probably be getting ready for tomorrow." Howard admitted, while getting up and putting his jacket on, Raj also admitted that he ought to be going home. This had left Leonard and Sheldon sitting awkwardly side-by-side on the sofa.

"well we can't play Dungeons & Dragons with just the two of us, can we?" Sheldon said in annoyance. "no, we can't. unless..." Leonard begins, but is interrupted by Sheldon "it was a rhetorical question, obviously we can't when Dungeons and Dragons is a four player game!". Leonard sighed and was advancing towards his room, when he receives a call on his phone from his mother.

A few minutes later

"My mother's visiting tomorrow" Leonard said to Sheldon in order to break the awkward silence that was filling the room. "why would this concern me other than the fact that there is an additional person in our apartment?" Sheldon replied, "I just thought you might have wanted to know" Leonard sighed, "I was wondering if you could spend some time with her later on so I could have some spare time?" He continued. "but I was going to go to the cinema with Amy tomorrow evening!" objected Sheldon, to which Leonard sighed and switched on the kettle to prepare some coffee.
