A Red Door

A red door is... striking.
A red door is bold.

A red door will beckon you

In from the cold.

A red door gets opened

When you've got the key.

But it isn't much help

When the key is with me.

A red door takes mail

On the days that it comes,

And sometimes graffiti

When found in the slums.

But this door is special,

Whate'er it appears,

Because it's my Granny's

And has been for years.
