A big problem I have being in my early twenties is drinking. I used to be able to drink, and now none of my friends can understand that I can't drink anymore. I can't even have a sip. I get the constant "why aren't you drinking?" "Can't you have just one?" They think it's going to change the very next day and my magical fairy godmother is going to poof and make me able to drink. Drives me nuts!
