Men at work(who can it be now)?

Question

Whats that song about, and what does he mean by ( I like it here with my childhood friend)

Answer 1

I thought it was about memories. You know how they sometimes come creeping back to you, and especially if they're not GOOD memories, they can really consume and ruin your day. You might want to hide from them

I thought the door of "knocking at my door" was your head (or your mind).

It works as a theory, I think.

Here are the lyrics:

Who Can It Be Now?

Who can it be knocking at my door?
Go 'way, don't come 'round here no more.
Can't you see that it's late at night?
I'm very tired, and I'm not feeling right.
All I wish is to be alone;
Stay away, don't you invade my home.
Best off if you hang outside,
Don't come in - I'll only run and hide.

Who can it be now?
Who can it be now?
Who can it be now?
Who can it be now?

Who can it be knocking at my door?
Make no sound, tip-toe across the floor.
If he hears, he'll knock all day,
I'll be trapped, and here I'll have to stay.
I've done no harm, I keep to myself;
There's nothing wrong with my state of mental health.
I like it here with my childhood friend;
Here they come, those feelings again!

Who can it be now?
Who can it be now?
Who can it be now?
Who can it be now?

Is it the man come to take me away?
Why do they follow me?
It's not the future that I can see,
It's just my fantasy

Oh...Who can it be now?
Oh...Who can it...Who can it...
Yeah yeah yeah

Answer 2

My first thought is that it could be a bill collector, knocking at my door...
