I was informed today at pick up that it's parents evening tomorrow (first time I'm hearing of this) and my time slot is 7.15pm! I immediately said that wasn't possible as that is past my son's bed time to which they replied "oh well". There are a few things I've been meaning to bring up with them anyway and my son isn't in tomorrow. Would I be unreasonable to demand a parent's evening meeting next time Im there for pick up?
