It is rather philosophical issue...such that what is ethics and how far can/should you take. It'll be rather disastrous to define it as cut and dry. It never is...

- I would say... how about (not) being honest to your feelings...is not that a lying?

- Telling your gf/bf or kid that you are 'proud' of them, while you are just trying to boost their feeling. 

- A nice gesture to make someone feel good...'how do I look (in this dress)?' .. 'you look great!"

- OR Even more contextually, checking on an answer in multiple choice question when you have no freaking idea what the answer is. 

I think it's all contextual..Not that I like people lying about things...but the society is/has become extremely utilitarian and one cannot survive with at least some kind of (white) lies. How far you take it...how low/high life one is..(as if there is a way to calibrate it).
