Temporarily Permanent...

I am trying to think up a lie. A good one too. A good lie has to be a couple of things. It has to be clever and believable. It has to sound plausible and specifically applicable to my life. If anticipated, one must try extra hard. Being stealth and dishonest are not overly simple tasks. I, however, was given an out. I was told I could say no. A simple no...but isn't that rude? No...I have to lie. Yes, I do. I understand the situation fully, and there is not another option. Whoever said it was right, the truth can hurt. And I am not a purportfully hurtful person. My lie cannot be overly complicated, and yet, not overly simplified either. There has to be just the right number of details without being obvious.
Hmmm... I cannot seem to come up with anything. A simple white lie can be so difficult to conjecture. A personal sickness? Too convenient. A family emergency? Too many consequences...It's a delicate thing, a lie. I mean, I would rather know someone has to be dragged to the christening of their long-lost cousin's fourth child than receive a simple no. Now let me see....what could theoretically happen to me tonight? Apparently christenings are only believable on Sunday mornings...
