For us it's meals out. We'll take a look at our budget and realize that we've been spending way too much going out for dinner so we make an effort to cook more at home and invite people over so we still get a sense of community. So where to you trim the fat? Cut down on a housekeeper? Eat in more? Organize swaps with your friends? Is anyone looking at downsizing their apartment?
