Telling the Truth

Let's talk about truth for a second. I once had a boyfriend who was intense about telling the truth. He (according to himself) never lied to me once and told me that he expected me to tell him the truth ALL the time. Obviously, if you love someone, you should be honest with that person; but don't people need to lie occasionally? Some things are just better left unsaid because they're unnecessary, or hurtful, or extremely personal...

For instance, one night a couple of guys approached me at the gym and asked me for my phone number. I told them no of course because I had a boyfriend at the time, so it was no big deal. When my boyfriend asked me what I had done that day, I left that part out because I knew it would only make him jealous. It was an unnecessary detail, the sharing of which neither of us would have benefited from. Thus, omitting the truth was a positive choice in this situation.

Have you ever been in a situation where you felt like you didn't want to deal with the consequences of telling the truth? In your opinion, should people be totally honest with their partners ALL the time? I still hold that there are occasions for telling the truth and occasions for side stepping it a little. ;)
