You start your bank holiday with a mission, go to Ikea and get that closet you have had in your mind for the last two days. Next step a good sushi lunch with friends. Day is going pretty well, isn’t it? Then karma bites. My mother gives me a call to ask me for help with a broken faucet. Sounds simple enough. I’ll go there after lunch to fix it, in the meantime can you run to the store and buy a new one?
