Red

"Red flowers are generally associated with love and affection...but you know, geraniums have another meaning."

I know. "Determination," right? I looked it up. Wanted to understand you better, I guess, and she defined you more than anything.

I didn't find "determination" anywhere. You know what I found? "Melancholy" and "sadness" and "sorrow". "Disappointment." "Recollection." "Stupidity": that's my favourite. That's the Scarlet geranium. They don't get much redder than scarlet.

But there was also "ingenuity". Thought that one fit. "Comfort" and "friendship", and "surprise meeting". And "happiness": that one had a picture. They're pretty, a bunch of hearts gathered together.

Appropriate.
