In theory we eat at 6:30pm, but in practice, it depends on work or shift patterns. Mostly, we eat at 7 or 7:15pm as if the OH doesn't finish work until 6 it can take him over an hour to get home.... I don't normally get home until 6:30 most of the time. We are lucky that my mum cooks for us during the week(mon-thurs), so it is ready when we get in.
