What Meng Yao wants to do is talk to Lan Xichen about reassuring the freshman indies that while Shanghai might be doing something sketchy, upon closer examination they're actually behaving perfectly reasonably.
But he knows that the problem will keep; the freshman indies are powerless, being freshman and indies, and while they wouldn't want to sit on the problem for weeks it can easily wait until Sunday to address, and it isn't worth the effort to trade their maintenance shifts.
So instead he's heading down to the cafeteria to sweep the floor.
When he graduates, he thinks to himself not for the first time, neither he nor his mother is ever going to have to sweep a floor again.
