And its force is especially powerful when it appears together with: The Bargain.
So there I am walking down the rainy Edinburgh street. Mining my own business, on my way to the bank. That's when I see the sign in the window: "£10 manicure with hand massage".
I try to be strong. Try to fight it. But I am no match for The Vanity an The Bargain, in a simultaneous ferocious attack.
I walk in, defeated. The man in the salon looks at me and smiles. He knows.
I make it to the bank on time.
And I look fabulous.
