When is a lie not a lie?

If I tell you that if you give me an apple I’ll give you some chocolate, you might think that was a decent deal and hand over the apple.  There you stand, licking your lips, anticipating a nice piece of chocolate.

What if, however, I didn’t tell you that:

• The piece of chocolate would be the size of a grain of sand
• The quality of the chocolate will be extremely poor
• You’re not going to get the chocolate until I decide to give it you
• I haven’t actually got any chocolate right now
• I’ll need you to pay for the chocolate upfront, actually
• I’m going to grub up your orchard

Have I lied to you?

Too late, I’ve got your apple and very nice, fresh and crunchy it is too.  To be honest, I wasn’t really expecting you to give it to me – and I didn’t really want it.

Oh!  I just found half a worm…
