Would you be willing to lie in order to surprise a loved one?

For a surprise date, maybe, or a present? Is the lie justified by the happiness your surprise will (hopefully) bring?

Bonus question: Can you think of any ways to successfully pull off a surprise date without lying? Let’s say you want to take your spouse to the movies, but want that to remain a surprise until you’re almost there.

I have a friend who will believe anything he’s told. It’s easy to surprise him, but I worry about taking advantage of that. Also, I like his personality. What if I turn him into a cynic?
