You said no,
and then you explained it. For what?

The no was fine on its own. You didn't believe that.

So you gave reasons. Then a reason for the reasons.

You call it being considerate, and some of it is.

But a long explanation starts to sound like an opening.

People walk through it. Not because they're pushy. You left it open.

You don't owe anyone the working out behind your answer.

Say it once. Then let the quiet do the rest.

It'll feel rude for about a day. It wouldn't have been.
