Fly on the wall

 Fly on the wall

I'd love to be a fly on the wall 

Is something I always say 

My nan actually taught me the phrase 

And still uses it to this day 

The more I think about it in detail 

I seem to love it more 

How much a fly can see 

When it is perched on a wall 

But a fly is seen as a pest 

Especially in Nan's house 

The hoover goes on and believe me 

She'd burn it to the ground 

So when we say we'd love to be a fly on the wall What I really mean to say is I'd love to observe yet be unseen and invisible
