Happy Birthday darkOne!

I totally agree with the others. Don't waste your money on coke. It's a bullshit drug like heroin and meth. You don't need to get yourself hooked on that crap. Some people do get hooked just from doing it the first time.
It's not worth it.

Buy yourself something nice, something that'll make you happy now and in the future.

And don't forget to send Grandma a Thank You!
