I think she's just getting old
On another note I've actually gotten to the point where I can really enjoy a beer, but I can't party and drink it unless I'm already drunk so I always start with shots or cider. It's just a routine I've had since I was younger and hated beer and it's only mentally: The beer tastes the same if I'm drunk, watching a football game with some friends or at a pre-party but my brain tells me that it's disgusting if I'm sober and at a pre-party so I just can't drink it...
However, maintaining your "drunkenness" with beer is way better than with liquor. You get a "softer" drunkenness... if you know what I mean
Chilling though is completely fine. I often take a beer while chilling with friends, playing music or watching a game (I never drink alone though).
I don't consider liking beer as a very adult thing to do, it's just a matter of getting used to imo. I also think it's more mentally than physically. Then, of course, there are beers whom you instantly fall in love with (Heineken, Guinness dark and Staropramen). :3
But really, maybe it's a mature thing to like beer, but I sure as hell don't see myself as a mature person, not even when I'm drinking.
I've been partying a lot lately but I haven't really been on MH after, which makes sense as I'm partying on Campus and I live 450kms away from it so I've ended up sleeping at other peoples places.

I will get better and make up for it, I'm sorry DDD, love you *smooch*
