Malvina Reynolds had a poem once. Ah, it's over here in THE MUSE OF PARKER STREET:

You can't run away
No matter where you go.
The world isn't big enough
For you and yourself,
And everywhere, that YOU comes tagging along.

You can't run away
From the ones you love.
For they are you, too,
You are the sum of what they think of you,
And if you run
They wonder for a while,
And then you grow less and less with every mile.
