Sheldon hit the ceiling unnerved away, got out of bed and sighed softly.
He quietly left the apartment and went down the hall to 4B.
As soon as he lay in Pennys bed he relaxed and fell into a light sleep.

As quietly as possible she went to shower quickly, put on fresh clothes and snuggled into bed.
Sheldon woke up briefly, pulled her back against himself and buried his face in her neck.
"It's so hard to sleep properly without you, Penny!"
