Spot the Difference

Spot the difference here
I'm the only one not smiling
I'm the only one afraid of dying
I'm not the one who's up there dancing
Or talking with stragers
Small talk with strangers
Normal. I'm so normal I'm depressed here
I'm the one who's better dressed here
I'm the one who has my health
Order coffee for myself
They don't look so strange to me
Except they're smiling all the time
Can you spot the difference here
Who has lost their piece of mind
Or peace of any kind
They're not worried
Not worried on the eve of destruction blessed by a lack of
Understanding
What they don't know can hurt them
With less upon their plate
They eat lunch while we wait
They don't look so strange to me
Except they're smiling all the time
Can you spot the difference here
Who has lost their piece of mind
Or peace of any kind
