I suggest to introduce a new Holiday – the national, or at least the City’s Flake Day. This is one day when you are not going to upset about your friends and dates canceling meetings on you. You will expect it. Everyone, including you, will flake on that day. You will cancel all your business with others on a very short notice by text without good excuse, and it will be perfectly acceptable. A good date for this would be right after April 1, the fools day. What’s better than being flaked on after you are being fooled?
