I get together pretty regularly with a group of four friends for dinner. I value these friendships and am glad that we see each other and catch up regularly. However, there is one friend who will often agree to the plans that we’ve made and then bail at the last minute, usually offering a flimsy excuse. It’s disappointing, especially when we have made special plans so that she can make it. We also rely on each person to bring a part of the meal, so when she cancels we have to do without or the host has to provide what she was supposed to bring. I’m not sure how to handle this. Bring it up? Let it go?
