Listen to music and talk at their house.
Go to see the next Starwars in theaters.
Go to a museum to see cool fossils.
Go out to dinner.
Go to get ice cream and other desserts.
Her trying to kiss you.
Her hugging you.
When the right opportunity arises.
When you got her a present.
Pay for an expensive dinner.
Sit through a really boring movie.
Spend two hours looking for presents at the mall for her.
Cook all her meals for her.
Sort through your music and delete all the songs she doesn't like.
