http://news.independent.co.uk/world/americas/article299639.eceStroll the aisles of America's greeting cards outlets, and you will find every weirdness imaginable - good karma cards, getting high on marijuana cards, cards commemorating such obscure festivals as National Hot Dog Day (next Friday, as it happens).
Loved ones of all varieties are catered for. Well, not quite all. When Cathy Gallagher, an advertising executive from suburban Washington, was casting around for a new line of cards to launch, she realised there was one category whose feelings went unacknowledged: adulterous lovers.
So, earlier this year, Ms Gallagher - who is happily married - started a company called Secret Lover Inc and developed 24 different cards for illicit paramours. There was the "please-leave-your-spouse-now" card. The "we-can't-go-on-like-this" card. The "I-wish-we-could-be-together-on-your-birthday" card. They consist of understated acrylic paintings with plentiful text on both the cover and the inside.
They made their debut at a trade show in New York in May and became such an instant hit she has barely been able to keep up with demand from visitors to her website. They are due to go into stores this summer.
