Goldfish Birthday Card

I have a friend who I've known for 20 years, I know when his birthday is, it's written in my diary, my online calendars remind me and yet somehow every single year I have failed to get a birthday card to him on time. So I designed this card for him but there must be other people out there who are equally rubbish at remembering birthdays, this year you can make up for it with the perfect birthday card. The message on the card reads "Happy Birthday - you thought I was going to forget again didn't you?"
