Analysis of Introvert

I'm here on my own, but never alone.
Am I caught in a trap?

I  like going out, with strangers about,
No one stranger than me.

I can talk to a crowd; my wife thinks I'm loud.
Can relate with the people I see.

But I don't need anyone,
It always is fun, but,
Really just to please.

I like it here, with a smoke and a beer,
Writing lullabies.

Problem is, I gotta wizz,
And I haven't got my eyes!
