["I told my husband that I was going to see a friend when I didn't. I went to a party planner's place.", 'Are you going to have a surprise party?', "Yes! I feel bad for lying to him but I would only ever do it for his own good.  Its nagging at me already though.  I might up the date of the party so I don't have to lie too much!"]
I know that is hard, but it's alright if you do it for the right reasons.  You all will be able to laugh about it when it's all over.  Have fun!
