What are some atypical ways people demonstrate love?

Sometimes I say please and thank you  when I ask my gal friend to make me a sammich or get me a beer..
But I do little chores like cleaning her cat's litter box or doing dishes or other minor jobs around her place.
One time I even let her cat in the house to show his love by presenting her with the mouse he'caught. 

My husband didn't do any cooking but he used to make the coffee or tea, and would always bring me a cup.
