Dear Mild Mannered Intellectual Husband,
it has come to my attention that, as of tomorrow, we will have been blissfully and legally happy for 6 years.
To reward your loyalty to our joint enterprise I'm sending you a 'My hot wife loves me' coupon, for you to redeem in a variety of male conversations about hot chicks.
I trust you'll enjoy your coupon and will keep loving me for many long years to come.
Your Hot Wife
PS: Before you start, no the picture *does not* make you look like a giant green slug.
And anyway, it's a good picture of me, which is the whole point of the voucher.
