If you were walking down a street

And you found an envelope

What would you do

If it was not addressed to you

I would find a post box

And

And what

What would you do

I would find a post box

What happens if you were unsuccessful

In your search for the said post box

Would you open the envelope

No

Why

As it might contain bad news

Taken

But this news might be good news

There is no answer to your question

As neither assumption is finite
