We talk about things we're afraid of (the future, that last Supernatural episode) and things we want to be better about (not using coasters, being more cheerful). But one of my favorite things is recounting old childhood memories. Some of them are so buried in the back of our brains that we are literally sharing something we've never told anyone before. We'll laugh about the stupid things we did that we thought were cool, and we look at our parents differently. Experiences are remembered differently once you're an adult, and especially once you're about to be a parent.
It's pretty great. Also, I took a breastfeeding class yesterday that was gloriously awkward. So there's that.
