Hey, accidents happen. You can't beat yourself up forever if you got someone's name wrong, sent an email to the wrong person or dropped something on someone's foot. These things are just part of living, so all you can do is make the best of any awkward situation you find yourself in today. You have the tact and charm necessary to get anyone on your good side. The best move after a big boo boo is to smile and offer a heartfelt apology: people know when you're being genuine.
