Ok so I sent out invitation about a month ago and most of my OH family have replied and said they are coming. My family on the other hand are something else. My parents haven't even replied and my sister has fobbed me off. I asked her if she had got it and she said that she would be posting the reply on Monday. That was 3 weeks ago. To top it off, my OH's uncle has now conveniently booked a holiday on the same day as the wedding despite knowing for 8 months that we are getting married. Am I stressing over nothing here? Do people actually leave their replies until the last minute? I was sure that people would reply straight away while its fresh in their mind. Maybe I'm just being impatient. What time scale did everyone else receive the RSVPs?
