What's the best white lie you've told or had told to you?  Not counting Santa, the Easter Bunny, or "no that doesn't make you look fat".

I was 3 or 4 years old and the on-farm butcher truck appeared in the barn lot to butcher a fat steer.  This was the first animal I witnessed dying, and like any kid that age, I was curious as to what was happening and why. 

The little white lie I was told:  the calf had a bad belly ache and was suffering, so they had to end his suffering.  For quite some time after that I was a bit worried I might meet the same fate if I had a really bad belly ache.
