Hmmm well it depends on who I was dealing with, and if there is a reason for me to uneccessarily hurt someones feelings. I guess there are polite ways of telling someone the truth. If for example a large friend of mine was wearing something that made her look heavier, I'd tell her, because I wouldn't want ppl making fun of her or whatever. I think when you're dealing with friends they expect the truth but sometimes its really difficult if you know it's gonna hurt them. I mean do they really care what a stranger would think? There are alot of pro's and con's in my opinion.
