We don't celebrate them but do discuss aspects of them. My view is that I expect good grades unless they show me they have worked hard and tried their best but still didn't do well.
In particular, middle DD does not always bring home great grades. If I know she tried, we'll talk about how much she learned. Usually it's more along the lines of we know you are capable, so let's work harder next time to show that.
DD16 is not making straight As anymore in AP classes now. It bothers her but we talk about how hard she is working & reassure her, that's fine, we're very proud.
