Lets speak about CHARACTER.
If you lie today.. simply because it is Aprils Fools what does that tell people about your integrity?
At least to me it ranks right up there with lying to your children at Christmas, Easter and tooth fairy time.. It says to me that your knowledge of what is true doesn't always mean you will do what is right.
As someone who is trying to grow good Character in a world that has frankly dismissed character as a needless frippery.. I want you to think about it.. Don't your kids see that, doesn't your co-workers notice.. Do you really think that people don't care that from time to time your word means NOTHING?!
So go ahead, April Fools, Christmas, and ANY OTHER TIME.. Be a lier.. You will see that Integrity isn't something you can turn on and off like a light switch and have it mean anything at all!
