Flirting at inappropriate times, Mostly at crime scenes.
Him winking at you when he does something clever.
Listening to him pay the violin at night.
Winning cluedo.
Arguing about cluedo.
Throwing away his cigarettes.
Elbowing him when he says something rude on accident.
Apologizing for him when he doesn't care.
Playing with his hair as a stress coping mechanism for both of you.
Being smarter than everyone around you and both of you knowing it.
Sword fights instead of argument.
Him being able to be open to you and never shutting you out.
Holding hands when you get anxious and him always rubbing his thumb over your knuckles to let you know he is there for you.
Getting to see his beautiful genuine smile and falling back in love every time.
Lots of hugs!
All the hugs!
Never too many hugs!
Saying "I love you" in a hundred different ways without ever speaking a word.
