Would you lie to spare someone's feelings?
If someone asks my opinion about something I will always tell them the truth, even if the truth isn't what they want to hear. If a person is offended because, for instance, I haven't enthused about something they are wearing, they have only themselves to blame for asking my opinion in the first place, if what they really wanted was to be flattered!
Normally I shrug it off when people aren't happy with my responses, but there was one time when it was most awkward indeed. When my father was dying he tried to make me promise to do something, which would probably have made him die happy, but I had absolutely no intention of doing what was requested of me. I could not have lived with myself if I had promised to do it, knowing full well I would never in a million years fulfil the request. It was not something he should have asked me to do anyway, and I had to point that out to him, which of course didn't make me popular. But HEY HO that is life.
