The version of the truth. You were late for a meeting due to lingering too long over your latte. There was a particularly busy rush hour that day, so you offer as your excuse, “Traffic was terrible today.”
Part of the truth. You don’t really want to go to the Jack-and-Jill wedding shower you were invited to, so you give as your excuse the fact that your family is coming into town that day. It is true they’re coming, but the shower will be long over by the time your folks arrive in town.
Technically the truth. Some lawyers are expert at giving reasons that are true but only in the technical sense of the word. It is possible, using this logic, that you only remembered your friend’s birthday 3 days after it was over. Your excuse may be that you think it’s much better to wish someone happy birthday in person. Technically that is true, but it’s not why you missed the big day.
