Lying is an inherently dishonest practice. People tell so many tiny white lies nowadays that they consider lying to not be a bad thing. People are like, "If my friend asks, does this dress make me look fat, then you should say no even thought it does because you don't want to hurt her feelings." However, my opinion is that the friend wants an honest answer. No one wants to wear an outfit that makes them look bad. Instead of lying, try to word the answer in a way that doesn't hurt a person's feelings so much. Say something like, "The dress doesn't really highlight your best features. I think you look great in so-and-so dress. I would really suggest it instead." Or something along those lines. Try to side-step the question by suggesting an alternative. That way you don't have to lie and your friend doesn't wear a dress that makes her look bad. I'd personally much rather have someone tell me that an outfit doesn't work for me then to have them lie and say it looks fine. I would hate having people snickering behind my back when I wore the outfit because it did make me look fat. I'd rather wear an outfit that looksgood on me. Lots of women ask that question for a real response and dont' want to hear a lie to spare their feelings. It would hurt alot more to wear the outfit and have people laughing at you for wearing something so off-putting.
There is usually no reason for people to lie. People just tell their little white lies because it is easier. If you mess up, fess up. If someone asks your opinion, either give it or side-step the question. But don't outright lie. It's dishonest and honesty is what friendship and respect are largely based on. If you don't have honesty, then you don't really have much of a friendship to begin with.
"A killer is hunting you down, (dangerous kililer that cant be stopped) and he is asking your friend the place you are currentlyliving. Do you want them to lie?...to save your life?"
Well, first the killer is likely going to kill you anyway whether you divulge the address or not. Why would you lie and give them ANY address at all? Lying about your friend's address is just going to send the killer to someone else's address. And those people would likely die by the killer's hands too. So not only are you dead but also some innocent civilians who just happened to have the wrong address. If the killer asked me for my friend's address, I wouldn't give them any address at all. That's not lying. That's just refusing to divulge information. More than likely you'll be dead anyway so why give any information to the killer. Just tell him to go shove it.
