Stereotypical Birthday Cards

Forgive my less than eye catching title and prepare yourselves for another rant. The other day I was trying to pick a birthday card for a friend and I realised that most of the cards for girls were about shoes, shopping, chocolate and 'getting drunk with the girls'. Things like 'Happy Birthday, have a great chocolate filled day, go shopping for shoes and then get pissed with your girlies!' Then there are the cards for men - 'Happy Birthday, look at big boobs and then drink beer with the lads!'
Who buys these cards? Who bloody makes these cards? Paints a pretty bleak image of men and women right? Anyway I resorted to a card with a photograph of a cat pulling an amusing face whilst sitting in a bowl of salad.
