I'm really not keeping secrets from her, but usually confessions consist of admitting to something that I know better than doing by now, and there is no justification for having done it anyway. Starting with " tangled with the rose bush, on purpose, again - aren't these scratches lovely?" just is not going to be well-received. Same with procrastinating things I needed to do and not having time to eat or sleep and living on caffeine. I know what I'm doing, and if I confess to running myself into the ground, when I know better, the confrontation is going to be pretty uncomfortable, and we've already been there a million times so there's no point. It can be productive sometimes, but usually not the best use of the time. Sometimes I do feel compelled to tell her, just to be honest, and lately I get confronted on why I chose to mention that, when I know where that's going to lead and I know that I don't like it much.
