The Number of Sprays Dilemma

Some perfumes are quite tricky when is comes to knowing how much to put on. Some start off strong and disappear with a whimper; some start off as weak as water only to ramp up in strength seemingly in direct relation to the impossibility of finding somewhere to wash them off.

How much perfume
Should I wear today?
One spray, two spray?
It's really hard to say.

I can barely smell it
But am not expecting cheek
So stow your bare audacity
And don't say that I reek.

I think it will smell better
If I spray some on my chest
So the unfolding of the perfume
Can be captured in my vest

One spray, two spray
Oh I'll give a couple more
Just to be on the safe side
As I head out from the door.

Some grow ever stronger
As the day wears on
Others never surface
However much I don.

Whatever choice I make
One spray or five or eight
I realise it's the wrong one
As I am running late.
