Many of us will have similar memories about our college years, and they involve making bad romantic decisions after consuming far too much alcohol. It's almost like a rite of passage. As it's probably going to happen anyway, you might as well embrace it and make it seem like it's part of the plan, as this girl has done here.
In years to come, she may come to regret the fact that she chose a t-shirt which suggested that she was anyone's after a few drinks, and then allowed people to take pictures of her wearing it that will now be on the internet forever. As long as she was having fun at the time, maybe that's all that matters! We bet people were lining up to buy her shots when she was out on the town, though.
