Merlin and Arthur do everything together.
While they may live apart, Merlin spends most of his time at Arthur's.
So much time in fact, that when he does the Tuesday food shopping, he takes his bags to Arthur's, not his.
On Mondays they go to the cinema together.
Wednesday's they go to the Library.
Thursdays it's the pub.
Fridays they go clubbing.
And the weekends consist of takeouts, DVDs and late nights curled up in warm duvets.
Everyone say's they act like a married couple.
Merlin thinks they are just good friends.
Arthur wish's that they were a married couple.
