I'm really glad you're enjoying the story so far. While you wait for my post though, here's a little exercise you can do.
Consider the various ways one can show affection for someone else with various levels of subtlety. Also consider the many different scenarios one could use each of these and their possible effectiveness. Note that subtlety employs many forms of simile and metaphor. It's up to you to decide which ones to use in the most effective manner.
Just something to think about. No need to write anything.
Do you have an exercise for me? 0_o
