Missed Waves

Hello 
You wave at me
Gently like a swaying blade of grass
Seconds drag on
And moments pass
Before I can think to lift my hand in reply
The regret will now linger
Crawling in a hot shameful, many legged entity 
Up my spine
And across my cheeks
Because before I could think to lift my hand in response
You had already passed me
And I was too deep in my own frustrations to pay mind 
To the fact
That to socialize fully 
Would mean to wave back.
