Carla, we are all adults. There is nothing childish about an adult choosing to drink from time to time. Just because it's not for you doesn't mean you get to bash those that do. There is a huge difference between an alcoholic that drinks from morning to night and someone who occasionally likes to have a drink. No where in the OP's was it mentioned getting shitty or even getting shitty all the time.
It's okay to have a different opinion and I respect everyone that has decided drinking is not for them. That's good for your health and we can do whatever we want to do as adults. But all I am asking is not to judge people that do. I think all of us get enough of people judging us for crossdressing, so we should know better.
