Ever say something and really, really wish you could just take it back?

I tend to push for complete honesty in relationships. For whatever reason, I want relationships where I can always say whatever's on my mind, where I can always be absolutely honest about whatever I do and think, and where the other person will be completely honest with me about what they think and do, as well.

I forget that some things are better left unsaid, and that timing matters a lot in the saying of others.
