Sweet Potato or Yam?

[Verse]
I stood by the produce lost in the aisle
Confused and bewildered about these roots in a pile
Sweet potato or yam which one in my hand
A question so simple yet hard to understand
[Verse 2]
I asked a kind stranger can you lend me your eyes
She smiled and said sure which one's your prize
Took a deep breath showed her what I'd picked
She nodded and laughed my choice felt so strict
[Chorus]
Sweet potato or yam I'm just so unsure
In a world of vegetables what’s the allure
Thought I had it right but I was mistaken
Embarrassment followed my confidence shaken
[Verse 3]
I walked to the checkout head hanging down low
Holding my produce my cheeks all aglow
The cashier she whispered don't worry dear
We’ve all been there it’s not so clear
[Chorus]
Sweet potato or yam I'm just so unsure
In a world of vegetables what’s the allure
Thought I had it right but I was mistaken
Embarrassment followed my confidence shaken
[Bridge]
I left the store wiser took solace in thought
Next time I’ll know better but today I was caught
Life's little lessons come in various forms
Even in grocery stores amidst edible norms
