To the OP, I just wanted to co-sign what a lot of people have said, you don't have to drink.
I'm not a big drinker, I literally drink probably 1-2 a year and I sip on a cocktail, I never even finish it. I prefer the non-alcoholic cocktails (love, love, love virgin strawberry daquiris).
My sisters knew I wasn't a big drinker. I would still attend events though. I remember attending a Derby Days activity, I didn't drink, but my sisters did. I just was there supporting them to win whatever activity it was (which I honestly don't remember, it was 10 years ago). So it can be done.
