A and B are sitting on the couch together
A: *starts to nod off, head hitting B's shoulder multiple times*
B: *blushing* You can fall asleep if you want. I don't mind.
A: *lays head on B's arm, falls asleep*
--5 min later--
A: *falls into B's lap*
B: . . . .
B: *shifts both of them so A is more comfortable*
A: *starts to wake up*
B: *lightly pets A until they fall back asleep*
