I used to be anti-hot liquids in general. Then I drank the magical beverage known as properly-made hot chocolate (made with MILK, not water). After that I stayed with my grandparents in Ireland for a while and they introduced me to tea. Really, really good tea. I have since branched out from black tea into green and white varieties as well. So very, very tasty.
Still don't drink coffee, though. I'm set for caffeinated hot beverages. Now, caffeinated COLD beverages (that aren't energy drinks or soda), I'm still working on.
Damn, now I need to go make me some Silver Needle. (The best tea. No, seriously. THE BEST.)
