Can u keep a secret?

Can you guys actually believe that I have only made two cards this week? Well, this card is one of them. 

The inspiration that I got for this card is the lock and key stamp from La Chateau stamp set. I thought that a 'can u keep a secret' card is a really good idea, instead of showing sympathy or congratulating someone, you use this card to tell somebody about your secrets. 

Happy cardmaking!
