Overview
A promise you recently made to a friend could be making you feel a bit uncomfortable today. But you mustn't let regret make you go back on your word. You should definitely be frank about any concerns you're having, but don't offer an ultimatum or force a change in plans. Just keep the lines of communication open, and make sure your friend understands how you're feeling. She or he might be equally disappointed in the arrangement, and might be able to suggest a better way.
