In an episode of Big Bang Theory, Sheldon tells his “date” (a double
date with Leonard) “time for bed”, leaving the disappointed girl in
the living room.
When the date asks to sleep in Sheldon’s room, he agrees, and, again
disappointing the girl, leaves for Leonard’s room.
This contradicts Sheldon’s standing policy “no one can go into my
room”. He even disliked it when Penny had to go into his room briefly
to find keys.
