What is with all these holidays that you need cards for? You don't actually need to give someone a piece of paper to inform them that it's christmas/their birthday/easter/pancake day. It doesn't actually make the day any bit better.. and they're usually filled with tired jokes that we've seen too many times before..
So please join me in a big EFF YOU to to these card companies and write the holiday of your choice on a rock so that you can give throw it at (or just give to) your loved ones.
