giving them food without them asking for it
randomly bringing them flowers
holding a door open for them
pulling out their chair for them
guiding them with a gentle hand on the small of their back
making them lunch to take to work with them
fixing their clothes or hair
talking casually about a shared future
showing them their appreciation for them
waiting at home to say hello when they come in
paying complete attention to them
giving them a casual, but thoughtful compliment
writing them a love letter and hiding it for them to find
showing them something that reminded them of their partner
humming a song to calm them down
giving them a quick kiss whenever they pass each other at home
casual grabbing their hand and swinging it back and forth
remembering something they told them
