Happy Birthday,
luminati!
I was going to send you something, but I figured you'd have little need for a large black thing with which to cover up unsightly snakes. :P
Seriously though, relax and have fun. Take some time off from studying and enjoy being (insert age here that is younger than me, it really doesn't matter what number- :P).
Or buy some cigarettes. I don't know why you would want to do that, but I suppose that given a certain inclination you could certainly do so.
